Kevin Rohan) Newsgroups: comp.protocols.tcp-ip Subject: (none) Message-ID: <8805190058.AA09533@FORD-COS1.ARPA> Date: 19 May 88 00:58:51 GMT Sender: daemon@ucbvax.BERKELEY.EDU Organization: The Internet Lines: 14 I'm looking for, if it exists as a standard, a document that describes the algorithm for mapping an IP class B or class C address into an X.25 address. I've got RFC 796 (that to the best of my knowledge has never been updated) and it doesn't cover X.25. I also have the NETINFO:X25.DOC and it covers the DDN's class A IP address, but I can't seem to find anything anywhere on the mapping of class B or C. It seems like gateways everywhere support this but where's the algorithm??? Thanks in advance!! Kevin Rohan jjkkrr@ford-cos1.arpa
