10.5: Disable DHCP-specified DNS servers
Authored by: siena on Aug 02, '08 06:55:02AM

Verified again (tcpdump on a 10.5.4 MacBook) ) and seen that the first DNS contacted is the OpenDNS server (208.67.222.222) added by an applescript ,not the DCHP assigned. Someone told me this was different in past versions.

10.5: Disable DHCP-specified DNS servers
Authored by: jonathank on Feb 17, '09 07:56:17PM

I am in Hawaii and the roadrunner dns is useless, I am trying to use OpenDNS. Sometimes OSX uses OpenDNS, sometimes it uses RR (and fails). Maybe there is an issue contacting OpenDNS but I doubt it. Seems like it arbitrarily selects a DNS server or maybe there is a timeout and OpenDNS is not fast enough (could be high latency over the pacific ocean)

I also confirmed this with tcpdump. the added DNS servers are checked first.
