Subject: Re: [ietf-dkim] Delegation semantics
I think that the NS suggestion is a bad one for policy reasons. I am
never going to delegate any part of my DNS. Space to a third party
and I don't think anyone else is likely to either.
Mailers routinely delegate subdomains to their ESPs right now. For
example:
$ dig email.orbitz.com ns
; <<>> DiG 9.3.1 <<>> email.orbitz.com ns
;; global options: printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 49736
;; flags: qr rd ra; QUERY: 1, ANSWER: 4, AUTHORITY: 0, ADDITIONAL: 0
;; QUESTION SECTION:
;email.orbitz.com. IN NS
;; ANSWER SECTION:
email.orbitz.com. 16536 IN NS
bb1dns1.edc.dartmail.net.
email.orbitz.com. 16536 IN NS
bb1dns2.ddc.dartmail.net.
email.orbitz.com. 16536 IN NS
bb1dns3.ddc.dartmail.net.
email.orbitz.com. 16536 IN NS
bb1dns1.ddc.dartmail.net.
