Qeustion to all you network GURU's: 05/20/88 Is there a standard for a loopback address. On BSD machines I've seen it is usually 127.0.0.1, however EXCELNA defaults to 127.0.0.0. Both let you override the default. I did not see any references to loopback addresses in the RFC index. Any comments or suggestions on where to look?

RFC 1009 defines the standard loopback address as {127,any} for
the {net,host} pair.

Hmmmm. Isn't RFC 1009 an obscure place for this information, which is relevant to many of us who never need to see the inside of a gateway? This deserves mention in "Assigned Numbers," and perhaps in "Address Mappings" as well, and certainly in the forthcoming "Requirements for Internet Hosts" RFC.

Well, when it comes to Internet numbers, I only do what I am told (Jon Postel is my boss). However, perhaps I misled you. If you will turn to the latest Internet Numbers RFC, RFC-1020, you will find the loopback address defined. Jon mumbled that he plans to move the special-number rules back to the Assigned Numbers RFC. So, yes, you are right. Bob Braden

If it's an "official" number, why doesn't it appear in hosts.txt and the domain servers? It would save a lot of people the hassle of configuring it in their local systems as a special case. --rick
