RFC1918 is a set number of IP addresses. If you are working on a private network lab that will be on the internet eventually or have parts on the internet and exceeds the total number of IPV4 addressing set aside in RFC1918, and IPV6 private addressing is not an option, what can you do? (I know it's a stretch, but I think it asks specifically what Brennan wants to know and what I'm curious about now)
You request the number if IP addresses you actually need from IANA (or the relevant registry). See RFC2050, which says: In order for the Internet to scale using existing technologies, use of regional registry services should be limited to the assignment of IP addresses for organizations meeting one or more of the following conditions: a) the organization has no intention of connecting to the Internet-either now or in the future-but it still requires a globally unique IP address. The organization should consider using reserved addresses from RFC1918. If it is determined this is not possible, they can be issued unique (if not Internet routable) IP addresses. DS
