DY> (Experiencing a "DUH!" moment.)  Yes, of course. It's zone data so =
only those entities handling zone data need to care.  In my =
still-annoyingly-jet-lagged mind, I made the classic mistake of equating =
"registrars" with "DNS hosting operators" because so many registrars are =
*also* DNS hosting providers.

> New RRtypes which do not require any "additional" processing, do NOT =
strictly speaking require resolver support, since resolvers handle =
unknown RRtypes. (Mark A can quote you the RFC, and I think has =
recently.)

DY> Ah, interesting. Where the proposed HTTP RRtype has behavior similar =
to the CNAME record, my assumption would be that resolver software would =
need to know what to do once it receives the record.  For that reason, =
wouldn't all the resolvers (or at least an extremely high %) need to be =
upgraded to support the new record?

> On the plus side, I can confirm at least one hosting/authority service =
will do this as soon as a stable spec is available (i.e. HTTP and a code =
point early allocation).

DY> :-)   Good to know!
