IPv6 Over Social Networks

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."

    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".

      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"
