IPV6
Advertisement
IPv6 is available now, but there is a big debate on when it will be fully switched over. I think the main reason it was thought up was because of the serious need in IP addresses after the internet boom. However NAT has managed to slow this down quite a bit so there may not be a need for it for up to 5 years.
However if devices such as cookers, fridges, you name it....start to connect to the internet themselves, they are going to need more IP's and IPv6 apparently would only run out if we started colonising other planets full of people.
As to the actual coding of IPv6 there are a few tid-bits in MSDN and basically you swap calls such as AF_INET to AF_INET6 and sockaddr_in to sockaddr_in6, but I'm not fully sure of the entire changeovers you do.
I think most of the info here is correct, I was told as well that it's most likely someone as big as Microsoft would have to start introducing IPv6 in a new OS and the problem is you have to change over all web based products to the new version because IPv6 servers/clients can understand and communicate with IPv4 clients/servers but IPv4 clients/servers would not be able to recognise commands from IPv6 machines.
It does have it's own website http://www.ipv6.org/ and some socket info ftp://ftp.ipv6.org/pub/rfc/rfc2292.txt
it's going to be a funny changeover from addresses such as 192.168.0.1 to 3FFE:2501:200:1FFF::7

I don''t think you stressed that enough....
IPV6 could support 19807040628566084398385987584 planets with over 17 billion IP''s per planet.

IPv6 has 4 32-bit words dedicated to IP address, so you can have 2^128 unique IP addresses. My networking professor said that is a number larger than the total number of atoms on the planet or something like that. As other people mention IPv6 is already available but not widely used because of all the current net infrastructure that works off of IPv4. You cant just force everyone all over the world to upgrade their hardware to support a new standard because not everyone can afford it. I think some countries like Japan have already switched their networks to IPv6.
I am sure if you do a quick search on google you can find a website that has the update IP header info for IPv6. Personaly I think that 4 32-bit words of IP address is overkill but thats just my personal opinion.
