Okay, better expand on what I am saying.. say you have a bunch of IPs from Linode, .. you 'might' want to indicate better what they are for..eg.. sharedhosting.hisdomain.com mailout.hisdomain.com etc.. If the PTR's still reflect the generic li1072-208.members.linode.com He probably won't get them removed from an RBL..
I guess there are people that don't configure reverse DNS on their Linode (et al.) IP addresses. But I can't fathom doing that for anything even remotely production unless "linode.com" was in my employer's name.
Usually this is ONLY done for a /24 or greater by upstream providers.
Ah. So maybe it's more they "won't" support it than "can't" support it.
(While it can get done for smaller blocks, you end up with that ugly double PTR record, one from the provider and one from your DNS server)
Please elaborate on what you mean by "ugly double PTR record". RFC 2317 Classless IN-ADDR.ARPA delegation comes to mind and I bet that's not what you're referring to.
Yes, we see that.. it does occur.. but pretty obvious usually. Take a look at the OVH guys with fake ownership.. but it can be used to help positively identify good operators, and that value is important as well.
ACK
Strange, wish Linode would pipe up on this on list..
Ya. I wish that more providers would be active on industry mailing lists.Thankfully I find that I can get some engagement on Twitter. But sadly, often the people that respond aren't able to do much. Though occasionally they do manage to unwedge things.
Some segments are REALLY bad, and other segments never generate a complaint.. They must be differentiating internally some of their customer signups..
I wonder how much of it has to do with age of the segments and / or VPSs therein.
If the hosting provider doesn't provide 'rwhois', speak with your feet.
Given their recent announcement of 20% rate increase on a lot of products / services, I'm probably going to be re-evaluating things.
Even GoDaddy offers it, and as much talk about bad GoDaddy, a person with a correct 'rwhois' can usually get off an RBL a LOT quicker.
