IPv6 Addressing
-
Let's see if I can ask this question coherently:
Let's say in a Global Unicast Address which is usually listed as 2000/3, does the /3 signify that a GU**** Address must begin with 001 as it's first three bits. IF that is true, then would an address that begins with a 3 as part of its first four bits (0011) also be a GU address since its fist three bits would begin with 001.
I hope that made some sense! -
Ed,
This is a little confusing but here's the breakdown:
2000::/3 = binary 0010 0000 0000 0000::/3
in theory the 3 you mention such as: 0011 0000 0000 0001::/3 wouldn't be another network but an IPv6 address in 2000::/3 network. Any address in IPv6 from 2000::/3 - 3fff::/3 would be apart of the same GU 2000::/3 network
2000::/3 = binary 0010 0000 0000 0000::/3
2001::/3 = binary 0010 0000 0000 0001::/3
2002::/3 = binary 0010 0000 0000 0010::/3
2003::/3 = binary 0010 0000 0000 0011::/3
...
3fff::/3 = binary 0011 1111 1111 1111::/3
a new GU network with /3 prefix would begin:
binary 0100 0000 0000 0000::/3 = 4000::/3
So if we used every 2000::/3 address for the GU...the next
network 4000::/3
Hope this helps you and not confuses you!
