Hrm, not much legit purpose? or not much the root/tld folks can do? I ask because essentially akamai's edgesuite (and I might have their product names confused some) seems to do FF ... or the same thing FF does. Doesn't it?I don't know of many if any who change the NS record quite so frequently without being bad guys.
ok, so 'today' you can't think of a reason (nor can I really easily) but it's not clear that this may remain the case tomorrow. It's possible that as a way to 'better loadshare' traffic akamai (just to make an example) could start doing this as well. So, I think that what we (security folks) want is probably not to auto-squish domains in the TLD because of NS's moving about at some rate other than 'normal' but to be able to ask for a quick takedown of said domain, yes? I don't think we'll be able to reduce false positive rates low enough to be acceptable with an 'auto-squish' method :( -Chris
