They are failing to do so, right now, at their own expense. Proper shutdown would delegate the apex of the DNSBL zone (or a the level above) to a nameserver with an address in TEST_NET (192.0.2.0/24) with a high TTL. This causes inattentive users to have a lot of failed lookups (fast fail or timeout, depending on whether/how they filter TEST-NET) and *probably* notice eventually, but without pounding the upstream nameservers with bogus queries. That tactic (and to some degree RFC6471 in toto) was devised in response to the "list the world" shutdown of an early popular DNSBL, whose operator had rooted the DNSBL zone right on a registered domain, and so could not do anything to stop the queries without sacrificing the whole domain. RFC6471's advice was informed by that history. > That does not necessarily mean that they will actually also truly do so - lip > service is a common attitude, unfortunately.

Here when it comes to sticking to RFCs. :-) There is no doubt that the Manitu handling has been poor and RFC-ignorant. -- Bill Cole _______________________________________________ mailop mailing list [email protected] https://list.mailop.org/listinfo/mailop
