Can anyone confirm that the entirety of these /16 networks (i.e.
NET-UUNETCUSTB35, NET-UUNETCUSTB36, and NET-UUNETCUSTB37) are all used
for dial-up by UUNET?  Are there any more?  I'd love to add them to my
TCP Wrappers config, but since I publish that list I'd like to know with
a bit more certainty than just "I heard it on NANOG"....

I wish all dial-up providers would use an easily recognizable (by TCP
Wrappers) subdomain for their dial-up port PTRs, and that they'd all
co-operatively publish these domain names in some common place.....

My current list of such subdomains is available down at the end of:
