airport primary/secondary dns
Hi,
I'm curious about how these 2 entries work together? First, I have noticed that if I put something like Google DNS in the second entry only (with the first entry being the default from my ISP) that it used Google DNS even though I have it listed second? Is this because I have no "static" value in the first entry?
Second, if I put a primary and secondary when does it get switched to the secondary entry? I assume if the first one fails but is this after 30 seconds and no reply or how exactly does it work?
I have very bad DNS from my ISP and that's why I'm trying to figure this out thanks!
