Well, here's what I suggested to UUNET and Genuity, which they mostly did:
To: routing at uu.net
Subject: please change your PTR RRs

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