what dns server do i need, and what is best
Posted on 2009-04-02
I currently have 1500 users, and growing, and seem to be experiencing DNS related issue causing a degradation of service. At peak times, clients on the largest VLANs cannot get to the DNS (off site). This is arbitrary and intermittent--happening on some computers all the time, and certainly more often at peak usage times.
this is a remote site, with limited bandwidth--so peak times don't translate to congestion on the lan side--but bandwidth limitations.
If this is a dns related issue, what would be the best solution--setting up tow local dns as forwarders? what kind of dns do i need (to accomdate forwarding traffic, and perhaps adding some local hosts)?
could i setup a private only dns to deal with local hosts, and then forward all other traffic to our isp's dns?
