Verisign definitely uses host objects, and _has to_ have a host object for any name that is referred to as a name server.  That's just how EPP operates.

I think I didn't actually understand your followup.  Is the problem that there is an out-of-bailiwick host object that has an IP address?  Is this a legacy object such that, for instance, the registry used to be authoritative for foo., bar., and baz. and now it is only authoriative for foo. and bar. but the host object is in baz.?  I wouldn't be surprised to learn there are such things around with old IP addresses, but they can't get published anyway, right?  I mean?…

… _how_ would they get "published accidentally"?  In what zone?  Glue records underneath baz. can't be published in the foo. or bar. zones no matter what: they're out-of-bailiwick and I'm unaware of any nameserver that would either publish such a record or, if it were received, accept it.
