[isp-dns] Re: Should I have to restart BIND for updates?

[jclements@...]

	We were not any sort of authority for that domain.  I should not have to
restart DNS every time a completely unrelated domain changes hosts.  How
would I even have known, had one customer not been trying to access the new
host?  Perhaps my cache TTL should be shortened?

I think something was wrong.  Perhaps I am just a pessimist.

//Actually, it sounds completely normal.  Name servers cache records they've
//retrieved recently and then keep them in the cache, typically until the
//record's TTL expires.  You just changed a record that was already cached
on
//your name server, but wasn't cached (hadn't been looked up recently) on
any
//of the other name servers you checked.

//Restarting your name server abruptly cleared the server's cache and
'forced'
//retrieval of the changed record.
