And, of possibly more importance to more people, is when people start claiming bogus authority for the reverse of a /8. For example, last week someone was claiming authority for 205.in-addr.arpa and 204.in-addr.arpa instead of for their appropriate /24s. A good quarter of the servers I checked had at least one of these bogus records, rendering reverse lookups for 204 and/or 205 non-functional and messing up anything that relys on reverse DNS working. I think this is a big deal when it happens, especially for the people using the address space it affects. Am I overreacting? If the server admin is unreachable, I think the provider should attempt contact and, if necessary, perhaps even filter the server. Most providers seem to have a "oh, that's bad. We'll get to it in a day or two" attitude. I tend to consider it a serious operational problem that needs to be fixed ASAP. On Thu, 23 Jan 1997, Dean Gaudet wrote:
Is something like a web page listing the "bogusns"s of the day in order? We could include the broken servers that claim to be root servers for non-existant TLDs like .space.

If you do, remove such records and change your DNS server software to something more reasonable. Dima fed up his ears with named's chronic inability to filter out bogus additional records
