The lastest RFC is RFC 1918 which states:
--- 3. Private Address Space
The Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of the IP address space for private internets:
10.0.0.0 - 10.255.255.255 (10/8 prefix) 172.16.0.0 - 172.31.255.255 (172.16/12 prefix) 192.168.0.0 - 192.168.255.255 (192.168/16 prefix)
We will refer to the first block as "24-bit block", the second as "20-bit block", and to the third as "16-bit" block. Note that (in pre-CIDR notation) the first block is nothing but a single class A network number, while the second block is a set of 16 contiguous class B network numbers, and third block is a set of 256 contiguous class C network numbers. ---
Some people said to use 127.0.0.0.. RFC 1700 states that the 127.x.x.x address space is for LOOPBACK ONLY, and should NEVER appear outside the host. So all of you using 127.0.0.0 as your networek.. better change it to one of the ones mentions above or get registered!
