Re: Domain names for ISP infrastructure links

So how do we name internal links in a way that is usefull for
all operators, and conforms to the A-Z 0-9 and "-" and can
be proposed as an RFC?

Well, here's what I suggested to UUNET and Genuity, which they mostly did:

To: routing () uu net
Subject: please change your PTR RRs
Date: Mon, 24 Jun 1996 06:38:08 -0700
From: Paul A Vixie <vixie () wisdom home vix com>

traceroute all over the world will soon show only IP addresses for
alternet routers.

alternet's router PTR RR names all have slash (/) and/or underbar (_)
characters in them.  BIND 4.9.4 considers these names "bad", per the
CERT announcement earlier this year.  please fix your names.  what i
use on my cisco backbones are names of the form:



        <iface> is something like <type><slot>[-<port>], i.e.,
                fddi0           -> f0           (no port number)
                ethernet2/3     -> e2-3         
                hssi4.21        -> h4-21        (subinterface 21)
        note that <iface> is optional since the router's loopback
        interface address (for IBGP) will just be the router's name.

        <router> is something like "CR2".
        <pop> is something like "DCA1".

        <toplev> is something like "alter.net".


        106.Hssi4/0.CR2.DCA1.Alter.Net  ->  h4-106.cr2.dca1.alter.net
