I've seen "glue" used generically to describe any record returned in a response from an authoritative server for which that server is not itself authoritative; that *would* include delegation NS RRsets, as well as associated address records. I've also seen it used to describe any record in a parent zone that describes a child, even if the parent *is* authoritative, as with "DS glue". Not saying either of those definitions is correct; just that they're not obviously wrong.

I call this "delegation following" (or sometimes "delegation chasing"), but I don't recall where I first encountered the term, and there may be a better one out there. -- Evan Hunt -- e...@isc.org Internet Systems Consortium, Inc. _______________________________________________ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
