IPv6 – The future of internet

I’m sure most of you would have heard about IPV6.We all....hmmm most of us use IPv4, the most widespread internet protocol till date. Beats to know that Ipv6 has been with us for over 10 years . Whoa!!! The future of internet made in the past.

The first to draw blood  were- linux and mac... Hmmm as usual windows joined in later (like cops of bollywood films.) anyways better late than never. But because of widespread use of windows most din have chance to use ipv6 until windows vista came into existence(though there are  clans wondering y on earth did it come into existence in the first place) . BTW Windows 7 candidate copy is out.. try it.. apparently it demands less resources ;)

Why Ipv6.??.

1:- because it exists.

2:-You’ll be forced to use it.

Ipv4  addresses can fill only 2 billion Address. It uses just 32 bit unlike ipv6 which uses 128 bit, that translates to about 3.3x10^38 addresses. Well !! for those who wanna stick with Ipv4. YOU are WELCOME!!!...but first the world must be annihilated .  WHY ?.. I’ll tell you Y? Its simple... more ppl, more computer. More computer, more address.. kill ppl then you’ll need less address..

We are all peace loving creatures... Aren’t we? so instead of annihilating the world, they coined IPv6. Soon IPv4 addresses are going to be exhausted. let’s all hope the post exhaustion era is smooth. AMEN . “The Next Generation Transition working group” AKA ngtrans is working on mechanism for smooth transition from IPv4 to IPv6. Wish I was working there. Don’t you?

IPv6 has a lot more new features. For instance IPv6 has fixed network address to 64 bits.. so no more class A,B,C stuff .

IPv6 brings in SLAAC(stateless address auto configuration) were in when u connect to  a network and if the router has been configured correctly then n/w layer configuration details are immediately sent but your router.....all this only if your router is capable of handling IPv6.

IPv6 doesn’t support broadcast. Well you can tweak its multicasting to create broadcast.

Ipv6  protocol mandates IP security...definitely safer than ipv4 where IP security is optional.

The best of all the is the jumbogram ....Ipv4 can only carry 64kb... But IPv6 can carry 4Gb

IPv6 addresses are written as eight groups of four hexadecimal digits. An eg IPv6 address

2001:0ea8:75e3:0170:1090:8d2b:0703:3341

  

Ipv6 loop back is ::1/128 corresponding to IPv4 ‘s   127.0.0.1

Dns servers will responds to Ipv6 queries with a Quad A record. Our beloved google also uses this... if u want google over IPv6 then mail them at google-ipv6@google.com..  (be sure you using ipv6 ).

If u wanna know whether u have IPv6 ...try accessing this site (http://ipv6.google.com/) if u are able to access it.. then well and good ....

Finally if u you wanna install Ipv6 then check  http://www.ipv6.org/ .  just a statutory warning...you may wreck your network by doing so.. Be aware of the workings of your network before trying it..

Happy IPv6ing J !!!
