Hrmm, no, that is called "Akamai", isn't it? :-)

I wouldn't presume to speak about Akamai's methods. Perhaps Avi's listening.

It's reasonable to assume that Akamai is deterministic, and is not dependent on the "Jeopardy Method" (who's-quicker-on-the-buzzer) that Bert Hubert asked in an earlier message. Stating more than that is above my pay grade. If you insist on deploying the Jeopardy Method, please remember to phrase your reply to a DNS query in the form of a question: rs@bifrost [2] % dig @192.148.252.10 19.252.148.192.in-addr.arpa. any ... ;; ANSWER SECTION: 19.252.148.192.in-addr.arpa. 5M IN PTR what.is.dhcp-19.seastrom.com. ... ---Rob
