Non-routed networks RFC/FYI

I remember a discussion a while back on having a 'well known' set of IP networks that would never be routed on the Internet (for sites assigneing addresses to hosts that never will get onto the Internet). Has something been written yet (a draft-fyi perhaps) . I need to do some renumbering, and would like to know which addresses have been selected for this category. -vikas (Vikas Aggarwal) vikas@navya.com ...rutgers!jvncnet!vikas -------------------------------------------------------------------------
