NS Records - are they queried in order or randomly?
Posted on 2008-10-07
I'm trying to find the answer to a fairly simple question ( I think its simple ) - NS Records - are they queried in order or randomly?
For example, lets say a DNS query comes through for my domain, four nameservers are listed:
Will ns2, ns3 and ns4 only be queried if ns1 is down?
I'd remember reading that it was random and this method could be used to provide simple load balancing for the DNS queries.
Thanks in advance!
