I was hoping someone could give me the RFC for non routable addresses
You want /all/ of the RFCs, right? RFC1166 -- Internet Numbers Covers addressing for Class D/E (multicast/experimental) traffic; shouldn't be used as source addresses. RFC1700 -- Assigned Numbers Covers fun networks like 0/8 and 255.255.255.255/32, which aren't nice for source addresses (or destination addresses outside of your network, depending on your viewpoint). RFC1918 -- Address Allocation for Private Internets Covers the 'private' address space definitions. draft-ietf-dhc-ipv4-autoconfig-04.txt -- Auto-IP configuration in ad-hoc networks: 169.254/16 Then there is the IANA test network, 192.0.2/24. (Anyone have an official reference to this one?) Then there is the unallocated IP address space, as determined by the IANA and the regional registries. And then there are a few other IANA-reserved networks. All of these address classes should be invalid as source addresses (except where negotiated in advance), and very few should be permitted as destination addresses (Multicast for example, should be permitted as a desination, just not as a source).
