I've just been around filling in some tag wikis for a bunch of DNS related tags, and I noticed the following:
a-record doesn't fit the same naming scheme as the rest. Probably because a is not a valid tag (doesn't make sense on its own).
Should we merge cname to cname-record and ptr to ptr-record (and for txt to txt-record, which I've actually already done because txt on its own is meaningless)?
