The only examples I have are: .abo.wanadoo.fr .adsl.wanadoo.fr \ --- haven't seen any of these in a long time, though .cable.wanadoo.fr / with the POP-Location coming at the forefront, after 'A', e.g. ANantes-106-1-5-107.w193-251.abo.wanadoo.fr AVelizy-154-1-44-113.w82-124.abo.wanadoo.fr APoitiers-152-1-35-162.w83-193.abo.wanadoo.fr or 'L' or 'M' Laubervilliers-151_11-15-186.w82-127.abo.wanadoo.fr LNeuilly-152_21-4-2.w82-127.abo.wanadoo.fr Mix-Amiens-107-2-8.w193-248.abo.wanadoo.fr or 'ca', which I assume is for cable: ca-angers-2-19.w80-8.abo.wanadoo.fr > Deutsche Telekom has an equally easy-to-understand scheme that ends in > dip.t-dialin.de (for their German dialups, anyhow). They must be filtering/redirecting outbound port 25, then; it's been some time since I saw any of their traffic here in the logs. Or maybe it's because they're using t-dialin.net now. <clickety clack> Yep. I don't see any t-dialin.de in 60 days, but tons of t-dialin.net hosts. -- hesketh.com/inc. v: +1(919)834-2552 f: +1(919)834-2554 w: http://hesketh.com join us! http://hesketh.com/about/careers/account_manager.html join us!
