Since all of the replies have been pretty close to the same (Use RFC1918 ...etc), I'd like to rephrase it to answer a curiosity of mine.
The answers seemed correct, rephrasing wont change current systems or policies to suit you!
RFC1918 is a set number of IP addresses. If you are working on a private network lab
Use anything you like, its private.
that will be on the internet eventually or have parts on the internet and exceeds the total number of IPV4 addressing set aside in
Follow the current policy for public Internet Address space, get what IPs you need, implement NAT where/if possible.
RFC1918, and IPV6 private addressing is not an option, what can you do? (I
thats the way it is, take it or leave it.. Steve
know it's a stretch, but I think it asks specifically what Brennan wants to know and what I'm curious about now)
IPV6 would seem to be the best answer overall since it has already been determined the solution for limited addressing, but there is still equipment/software and such that does not support it.
Brennan, is a mix of IPV6 and IPV4 private addressing an option for you? I do have to agree wholeheartedly that using address space not assigned to you is unprofessional, and will cause someone headaches later even if it is not you.
