Using the DNS protocol does seem traditional here. Contracted TLDs provided password-protected FTP downloads of compressed master zone files starting at least two decades ago.
Sure, because that’s what Verisign (Netsol) offered, not because it was a particularly good idea or well thought out.
CZDS is a putatively better replacement for FTP that avoids every TLD having to manage credentials for every client.
CZDS as a credential management system would appear to be independent of how the data access authorized by those credentials is performed.
A few of the TLDs added in the first rounds still use FTP, including .aero and .post.
Yes, a protocol not even the IETF uses any more and which support in browsers is pretty much gone.
If you want more background, just ask.
If it’s relevant, perhaps. Ah well, enough windmill tilting: having some familiarity with these things and no particular dog in this fight anymore, I’ll just go make popcorn. Regards, -drc
