Swiss To End Use of Nuclear Power

I'll rent you a solar system for only $1,000/day, but you'll need to find your own transportation.

If all you need is a backup set of optics, just make the pilots wear an eyepatch.

Last Days For Central IPv4 Address Pool

paul248 Re:How about... (376 comments)

So, when everything's on IPv6, and you want to play an IPv4-only game, you'll first have to establish an IPv4 VPN between the players? I suppose that sounds feasible, but someone will have to write the software to make it easy.

Last Days For Central IPv4 Address Pool

You do realize that the ISPs would be the ones doing the prioritizing, right?

Google To Push WebM With IE9, Safari Plugins

paul248 Re:Okay, good... (413 comments)

Most people are probably going to be happy using browsers that have both codecs

Which browsers would those be? I thought Chrome was the only one with both WebM and H.264.

After IPv4, How Will the Internet Function?

paul248 Re:It will prety much suck for quite some time. (320 comments)

It's difficult to manipulate binary digits in hexadecimal, too. I don't see any advantage to this.

Every hex digit represents exactly 4 binary digits. If you flip a bit in a hexadecimal number, then exactly one hex digit will change. To know how it will change, you only need to remember the binary values of 0-F.

With decimal, you could flip a bit and change every digit in the number.

After IPv4, How Will the Internet Function?

paul248 Re:ZOMG THE SKY [isn't] FALLING! (320 comments)

You listed 17 /8 blocks in your post. If you managed to reclaim every single one of those, you'd almost make up for IANA's 19 allocations in 2010.

And let us know how it goes when you try to take those addresses from the US military.

After IPv4, How Will the Internet Function?

paul248 Re:It will prety much suck for quite some time. (320 comments)

Using a hexadecimal address was pure stupidity.

Hexadecimal is used because a network is designated by an N-bit prefix, and it's *much* harder to manipulate bits in decimal, especially when each number is 16 or 32 bits long.

And using the colon for address separation is equally as stupid since that is how we designate port numbers.

Once you've gone to hexadecimal, using dots to separate the address leads to ambiguity. Is a.b.c.d.e.f.beef.de an IP address or a hostname?

it is pretty much unrememberable

With IPv6, your network will have its own 48 to 64-bit prefix. Once you remember that prefix, you can choose your suffixes to be as simple as you'd like.

you omit parts of the address ... but ONLY once!

You can only omit one run of zeros, because otherwise the length of each run would be ambiguous.

Free IPv4 Pool Now Down To Seven /8s

paul248 Re:Maybe I'm being naive... (460 comments)

When IPv4 was first developed, subnets were only allocated on 8-bit boundaries. Since CIDR rolled out in the 90's, the subnet length is now arbitrary, and working with subnets requires doing tedious decimal-binary conversions in your head. It's a mess.

IPv6 uses hexadecimal, because a hex digit represents exactly 4 bits. This makes the CIDR math really simple.

Now, what if we used hex with dots? Is a.b.c.d.e.f.beef.de an IP address or a hostname? Hell if I know. That's why we use colons now.

Free IPv4 Pool Now Down To Seven /8s

paul248 Re:The most surprising turn of events (460 comments)

And the second approach (a reverse SSH tunnel) only works if you have that server at work with a public IP. What happens when you want to connect to your friend's computer, which happens to be behind a different ISP's NAT, or even an overlapping RFC1918 space within the same ISP?

You basically have to lease a public IP on a server somewhere, to accomplish things that should be trivial.

Vint Cerf Calls For IPv6 Incentives In UK

paul248 Re:new act (164 comments)

This method would actually have worked if the people who made IPv6 hadn't decided to make the standard backwards incompatible.

How would you propose to make IPv6 backwards compatible? How can a device that only understands 32-bit addresses send a packet to a 128-bit address, and what problem would it solve that NAT64 doesn't?

As it is, IPv6 must be run in dual-stack mode, which means that even if you've got an IPv6 address, you must also have an IPv4 address.

T-Mobile disagrees. They're deploying an IPv6-only NAT64 network as we speak:

Vint Cerf Calls For IPv6 Incentives In UK

paul248 Re:Call me retro (164 comments)

The actual number of addresses is a red herring, since every user will be assigned between 2^64 and 2^80 addresses.

For all practical purposes, IPv6 supports about 64K times as many users, but each user can have an unlimited number of devices.
