Some years back people thought we would run out of internet addresses normal addresses have four fields ranging from 0-255 and many are restricted or owned in large groups.

So they developed a new ip protocol which has a much larger number of addresses called ipv6 there are two major reasons it has not caught on.

Expensive network equipment at the time could not route (move around) ipv6 addresses and alternate solutions have been created (like network address translation). Network address translation is what allows a company of 500 people to only own a few ip addresses yet put every machine on the internet (if they desired to do so).

So now MS has decided to turn both ipv4 and ipv6 on by default so when you type freerepublic.com dns servers will get two request one for the ipv4 address and one for the ipv6 adderss. I would expect MS to turn off ipv6 by default before to long its just not needed yet..
