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: http://www.robohack.planix.com/~woods/hosts.allow.txt -- Greg A.
