Re: [anti-abuse-wg] Reverse DNS delegations
>>> Why isn't it possible to gain a delegation by proving number >>> assignment? >> Because your ISP can't be bothered. > Is such unbotherability legitimate? these years, it is one of the things when considering a provider from which one gets address space. part of the problem is that this used not to be the case. "rdns is not really useful" was the common thought. so many isps did not pay it much attention. now, more and more services are using rdns mapping to defend against crapola. so it has become useful, and quite needed in some cases. but it is notalways easy to justify to management the costs of cleaning it up, often involving your provider, sometimes your provider's provider, and on up the chain. i have three /48s from an upstream. rdns is delegated, whew! but they are not dnssec signing. this has yet to cause pain, but i expect it will somewhere down the road. randy -- To unsubscribe from this mailing list, get a password reminder, or change your subscription options, please visit: https://lists.ripe.net/mailman/listinfo/anti-abuse-wg

There's no law against bad customer service... usually the market will eventually fix this (as in "some other ISP will offer IPv6 and proper reverse DNS"). For reasons not clear to me, Italian ISPs do take their time in rolling out IPv6... so maybe a bit more patience will get you there. That's right. Big ISPs play big ads, but only serve mass users. Small ISPs exist, but are hard to find and don't properly advertise what services they do. (This said, sending mails over IPv6 is a bit of hit and miss anyway, with Google inventing new requirements on IPv6 connections that are not there for IPv4...) I'm trying to use IPv6 only when there's no IPv4, but at times a DNS delay can make the server make the wrong choice...

Because your ISP can't be bothered. Is such unbotherability legitimate? I appreciate the fact that my provider endowed me with a bunch of IPv6 addresses. Previous ISPs couldn't put up with it. However, to have addresses and not being able to use them is not much of an advancement.
