You'll see 'abo' for 'cable', perhaps? as well as 'cable'. But for most
abo = short for "abonnement", that is, "subscription" / "subscriber" Just means its a pool of IPs assigned to users, I guess.
Yes, Romain Komorn was kind enough to tell me this offlist. Thanks.
Dunno. Don't have many examples of those, as I block most traffic from there, and what I didn't block didn't often have rDNS anyway. The one net.cn example I have, nova, named all of their rDNS with user.nova.net.cn - yep, that's it - what every host is named.
And there's a vietnamese ISP that was clever enough to give the same rDNS - "localhost" - to all their IP space. Don't know which one of the three ISPs there does this, but as APNIC 20 is in Hanoi, I'll most likely find that out for myself.
Yep - got a rule to block stuff from them and everyone else who does something that stupid, too.
FPT Viet Nam uses 'adsl-pool-xxx', 'adsl-fix-xxx', and 'dialup-xxx' (yes, the x's are part of the actual name, not a placeholder for the numbers).
So its not FPT Vietnam, but one of the two other ISPs there
They may use it, too. I dunno. It's not reliable to assume that any one given network always has the same rDNS naming conventions.
'bredband'. The Japanese use 'flets' and 'ftth', the Dutch and others
ftth = fiber to the home. flets is also some kind of fiber.
infoweb.ne.jp uses ftth, as does solcon.nl, onsnet.nu, and a few US ISPs, such as brightohio.net, cvalley.net, and surewest.net. nmt.ne.jp uses flets, as does across.or.jp, netwave.or.jp, dsn.jp, alpha-net.ne.jp (which also apparently uses "bflets", and incl.ne.jp. Google suggests others do, too, but they haven't come across my radar yet, or don't use it in rDNS naming. -- 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!
