IPv6 Over Social Networks

The Internet 102

An anonymous reader writes "A new RFC has been published this morning to significantly speed the deployment of IPv6. With IPv6 over Social Network (IPoSN), '[e]very user is a router with at least one loopback interface,' and 'Every friend or connection between users will be used as a point-to-point link.' It is noted that latency on the network can be very high, though."

With 6.5B+ people on this planet IPv4 won't last forever. Moving from IPv4 is like moving from 32 bit to 64 (128 in this case). Simple. Unless your using Vista, of course.

Re:The real joke is (0)

Anonymous Coward | more than 5 years ago | (#27424087)

We're probably about where we were in moving towards ipv6 as we were towards moving to 64bit in 2006. There is pretty decent software support for it, but it is by no means universal, and its definitely possible for someone who has a specific need for it to use it. People are now using 64bit operating systems all the time, especially as RAM above 3GB becomes increasingly common. Probably in the next 5 years you're ISP will ask you if you want a block of IPv6 addresses or a single IPv4 address. A few years after that, you'll have to ask specially just to get an IPv4 address.

Re:The real joke is (2, Interesting)

Anonymous Coward | more than 5 years ago | (#27424651)

My 32-bit applications work just the same on my 64-bit operating system. If they didn't I would still be using the 32-bit operating system right now and so would just about everyone else I know.

IPv4 applications are incompatible with IPv6 without modification. To this day there continues to be plenty of new software and hardware released with IPv4 only support.

I believe that at some point in the distant future we'll switch but to compare the IPv6 transition with moving to 64-bit is fundamentally absurd.

Re:The real joke is (2, Interesting)

ppanon (16583) | more than 5 years ago | (#27425147)

My 32-bit applications work just the same on my 64-bit operating system.

That's because your operating system is hiding some of the thunking that happens between 32-bit apps and the 64-bit kernel.

I believe that at some point in the distant future we'll switch but to compare the IPv6 transition with moving to 64-bit is fundamentally absurd.

The IPv4->IPv6 equivalent to the 32-bit->64bit thunking are IPv4->IPv6 gateways that - surprise, surprise - are in use so that IPv6 network clients (which are more widespread in Asia because they don't have enough v4 address space allocated) can access IPv4 hosts across the rest of the Internet. If you want to run your legacy IPv4 apps, you'll be welcome to do the reverse: run them on your private IPv4 network behind a NATting firewall/protocol gateway while the rest of the Internet runs IPv6.

Forgive any terminology errors, but please do correct them, as well as misconceptions and mistakes of all kinds; there's no point spreading misinformation about systems that are already very slow to be adopted. ]

That's not entirely true. You *can* use IPv4-only systems to reach IPv6-only systems in some special cases, but it is a kludge... http://en.wikipedia.org/wiki/IPv6_translation_mechanisms [wikipedia.org] and http://tools.ietf.org/html/rfc2767 [ietf.org] for more info.

Once all backbone routing and major website servers support IPv6 out-of-the-box, all of the old IPv4-only machines can be NAT'd during the (long, painful) migration period until they are eventually replaced. Sure, NAT makes things more complicated and can be more of a PITA for security and logging, and it arguably breaks DNS in subtle, frustrating ways, but there are already working systems out there.

Everybody with a linksys/dlink/etc gateway to stick multiple PCs on a single outside IPv4 address is already using sophisticated NAT-like mechanisms; when's the last time you had a masquerading problem that couldn't be easily fixed?. Using a hashing algorithm to do IPv4-to-IPv6 NAT actually breaks fewer application-layer protocols, though at the expense of requiring DNS hacks...

Earth President Barack Obama welcomed the representatives of the Galactic Brotherhood to Washington, assuring them that the many wars on Earth were now to be conducted entirely by robots, though the robots would be carefully monitored and pulled out of battle and granted citizenship the moment they achieved sentience. He also offered the galactics free access to Google, with only the requirement for tasteful contextually-attuned text advertising to be imprinted on their DNA.

The reactionary forces of the twentieth-century United States finally conceded defeat and shut down the Five-Year Plan Tractor Plants of Detroit, where ridiculous oversized transport was bashed together by semi-literate peasants between fifths of vodka from the nerve gas factory next door, and the Five-Year Plan Software Plants of Redmond, where ridiculous oversized operating systems were bashed together by semi-numerate fresh graduates between fifths of Red Bull. The record and movie company back catalogues have been placed into the public domain for the preservation of human culture and the comic-book capitalists of Wall Street have been sent to calming, soothing, humanistic re-education facilities. "We'll teach them to love again," said Mr Obama.

Robot housecleaners are now universally available at quite reasonable prices. The robot companion for your child, designed to say "I LOVE YOU" while the child hits it repeatedly, was an early release for Christmas 2007. The new model features the voice of Justin Fletcher from CBeebies and is designed for parents to hit repeatedly.

Future innovations for the century include the rise of the Great Old Ones from their eternal sleep to take back the Earth and consume the souls of all humanity, first driving them slowly insane. The citizenry is being prepared for this eventuality using repeated broadcasts of In The Night Garden.

Being able to remember the freaking address is the biggest problem, IMHO. It does offer much more than ipv4, but there's something to be said about the damn addresses - yes in a perfect world we all use DNS, but it's quicker sometimes to just use the IP.

Actually, I just thought, what if there was a new ip version you could use A-Z,0-9, maybe limited to so many characters per octet & w/ the 0 suppressing like IPv6, you could have a shitton of address space, but real ACTUAL READABLE ip addresses like omg.icanfinally.readthis.shit or address.city.state.zipcountry or something...

I find it amazing that more ppl aren't swtiching to IPv6, the space is projected to be gone by 2012...wtf are we doing when China needs more address space? NAT HELL?

Well, sort of. ff02::2 is the link-local all routers muticast group. You can ping6 that address to get the link-local address of your router.

Of course, you can also you router advertisements to have your routing table automatically populated. RAs are nice for home networks.

Re:Admins not adopting IPv6 (2, Insightful)

gbjbaanb (229885) | more than 5 years ago | (#27424153)

forget the admins, its the home routers. For everyone who wants to adopt IPv6, there's a shitty cheap router that simply doesn't support it. Unfortunately, the fact that the internet still works is enough to justify not buying a new one (not that there are many about).

If my router supported it easily, and I could just get myself an IPv6 address, I'd be using it. As it is, it requires some hassle, so I don't. That applies to the millions of ignorant users out there who wouldn't know how to set themselves up with IPv6 too.

So until there's a critical mass of IPv6 capable routers, no ISP is going to bother with it, and so no router manufacturer is going to bother upgrading them. The only way I can see it working is if someone starts marketing IPv6-capable routers as somehow better/faster/newer/future proof, then the marketing war might just drive adoption. Either that or the need for many non-NATed IPs per user in the home (eg phones).

Re:Admins not adopting IPv6 (1)

mariushm (1022195) | more than 5 years ago | (#27426205)

I'd like to have ipv6 but UPC (Chello in NL and some parts of Europe) has no plans to support it at this time.

They did deploy new cable modems since a year ago because they planned ahead to switch to DOCSIS 3 and in a few months they will do that. Towards the end of the year they plan to go for 50 mbps down / 10mbps up.

I don't know if these cable modems do support ipv6 but if they don't they'll probably just bring fiber to the premises (the apartment building) and pull utp cable in each apartment) so this will probably be 2-4 years from now when the other ISPs in the area will offer much better speeds compared to what they'll offer.

For years it has been like this. Then suddenly one year there were no April fools stories on 1 apr that year. This 1 apr, all stories are Aprils fools... Some moderation would be nice. But hey, it's only one day...

the IPv6 global address of the router loopback will be a /64 prefix (such as 2001:db8:face:b00c::/64) followed by the SNA identification

What was true in 2002... (1, Informative)

Anonymous Coward | more than 5 years ago | (#27425889)

"You find that you can't reach the CNN servers or the Google servers or your company's web servers."

not anymore completely true. try ipv6.google.com.

"every administrator of a client on a public IPv4 address---has to go to extra effort to acquire and enable a public IPv6 address."

every IPv4 address gets a /48 6to4 IPv6 prefix. (putting the discussion of 6to4 itself aside).
This will likely get you the v6 connectivity in half a day.

Though of course it's not the way to go for a large site. But hey, the "extra effort" does not involve the rocket science. Talk to your ISP.

"Wake up, folks: The ``combined v4/v6 network'' is a bad joke."

fire up the wireshark on your network which has hosts running Vista (Or try Win7 beta which there are some positive comments about ?) or a reasonably recent Linux distro (couple years?) or if you want to do it with style, a Mac. :)

"ping6 -I FF02::1".

Once I configured the router - Vista, Ubuntu, and the wife's Mac I did not need to touch at all to get the IPv6 connectivity. Can't say about Win7, I have a luxury of using *nix exclusively @work and @home for the past 5+ years - Vista was just an entertainment experiment as it came preinstalled with a new laptop I am using now under Linux.

"If you want IPv6 to succeed as a global network, you have to figure out how to make an IPv6 address just as useful as an IPv4 address."

There are already applications that are IPv6-only by nature. 6lowpan, for example. There's no "4lowpan", it's IPv6-only. There are others.

Though I respect djb for his skills, I think there are some updates that need to be done to the text.

I can imagine an introductory computer networking class being taught with this, with the students passing IPv6 messages over Facebook. Of course, some mechanism is needed to check for their correctness.

sbeckstead (555647) | more than 5 years ago | (#27424811)

Not nearly as good as the old TCP over carrier pigeon. With the birds there was much higher latency (measured in days or weeks sometimes) and the packet loss could be attributed to other wildlife, or poor training of the carrier. But OK I see it, this one could work.

Pigeons are layer one devices, remember - so they carry a layer two protocol, namely 'IP'.

ipv4.5? (3, Interesting)

r_naked (150044) | more than 5 years ago | (#27425025)

Was there something wrong with coming up with an addressing scheme that DIDN'T involve hex?

For example, go 64bit and use 16bit "hextets" -- 512.512.512.512. With that scheme you would have full backwards compatibility by using good old standard CIDR. If someone owned 1.255.255.255/8 today, with the switch they would still have that allotment, but we would now have 1.511.511.511/8 available as well. Am I missing something really obvious here?

For that matter, if we REALLY needed 128bit, go with either 32bit "somethingtets" -- 1024.1024.1024.1024...

Again, I would really like a network engineer / programmer to explain why this wouldn't work.

Who had the bright idea that we had to use hex for ipv6 AND have it not be backwards compatible.

From the people I talk to, the biggest reason they haven't gone ipv6 on their home networks is "because then I have to think in hex", with the secondary reason being "there is nothing available on ipv6 that isn't on ipv4 anyway".

Thanks,

Because IPv6 addresses are long enough in hex without having to have even longer and variable length decimal digits.

Fixed size hex blocks also makes it easier to do zero suppression, meaning (for example) the default route is written as ::0/0 instead of 0.0.0.0.0.0.0.0 and all-routes is ff09::1 instead of 65289.0.0.0.0.0.0.1

Hex is just easier.

Also, TCP and UDP are backwards compatible - Applications don't really care (apart from a few brain dead apps that want to internally process ipv4 addresses) if it's 4 or 6...

You said 'go 64 bit' - where are they supposed to go in the ipv4 packets we have, where addresses are 32 bit? How does being '64 bit' make it in anyway backwards compatible?

IPv6 has gone '128 bit', but it otherwise "not that different"

Re:ipv4.5? (2, Informative)

Anonymous Coward | more than 5 years ago | (#27426739)

Because hex is a better, EASIER representation of the binary that actually encodes the address. Ever tried to use the 192.168.0.0/8 notation? Did you notice how it's really confusing with decimal notation?

Frankly, if you can't wrap your head around hex then you shouldn't be using IP addresses. It's called DNS, learn it and love it.

Additionally, it is (sort of) backwards compatible (as much as it can be, without neutering it)- http://en.wikipedia.org/wiki/IPv6#Transition_mechanisms

"As an exception to standard IPv6 addresses notation, IPv4 mapped addresses are commonly represented with their last 32 bits written in the customary dot-decimal notation of IPv4, appended to the standard IPv6 notation of the leading bits, e.g., ::ffff:c000:280 could be written as ::ffff:192.0.2.128."

Re:ipv4.5? (1, Insightful)

Anonymous Coward | more than 5 years ago | (#27427021)

You might want to recheck your arithmetic ;) (hint: 2^16 isn't 512.)

Hex is a lot more compact, and easier to verify than decimal addresses. Ever tried to write a regex to match only valid ipv4 addresses?

And anyway, doing that doesn't give you backwards compatibility with anything - you still have to lengthen the IP header, meaning you'd have to have a transition anyway.

cobbaut (232092) | more than 5 years ago | (#27427997)

Because hextets would be written as 65536.65536.65536.65536 instead of 512.512.512.512

Re:ipv4.5? (0)

Anonymous Coward | more than 5 years ago | (#27428817)

Two reasons why the backward compatibility you think would be there isn't:

The socket structure containing an IPv4 address are actually just a 32bit unsigned integer. Dotted decimal notation is just to make life easier for us humans. Same for DNS. Overflowing an integer (i.e. trying to put a number larger than 2^32-1 in it) just makes it roll over and you end up with your_number modulo 2^32.

The other reason is that MANY programs sanity check the input of a dotted decimal IP address. The programs themselves would have to be modified to allow your "larger octets"

Could IPv6 be a playground for virus/trojans ? (1)

moogoogaipan (970221) | more than 5 years ago | (#27430515)

I love the idea of having more IP addresses but I fear the dangers of exposing our systems to the public net. NAT provides, at least, some sort of firewall for me. Sure, IPv6 can do NAT too but if I don't need it, why configure it? Just plug my PC into the public network and you're online with a public IPv6. Yeah, and that's what I think can be scary.

Re:Could IPv6 be a playground for virus/trojans ? (1)

TCM (130219) | more than 5 years ago | (#27433115)

Sigh, can we let the uninformed posts die please? NAT has got nothing to do with a packet filter.

You can do NAT without a packet filter, you can do filtering without NAT.

What prevents you from using a stateful packet filter with IPv6? Exactly, nothing.
