Hi

I'm puzzled a little - i see in my zone AAAA glue records with
link-local addresses. I think it is not good, but no rfc mentions
about link-local in glue.
Could someone tell me best practices for link-local in glue?
Well, some things are so obvious we don't state them explicitly.

If an address is local *only* to a particular link, then it's not going to be useful for anyone else who doesn't happen to be on that link. Right? So why publish something that's useless to the vast majority of DNS consumers?

There is an *Informational* RFC (4472) which "outlaws" link-local addresses in DNS (Section 2.1), but you probably won't find anything in Standards Track due to the "obviousness" factor.
