Hi,
Please could I have some advice about how the below example configuration would
work:
forwarders { A.B.C.D; E.F.G.H; };
What I wanted to achieve is that one of the IP addresses to be used as a
primary DNS server and the other IP address to be used as a secondary DNS
server.
I have had differing results from testing that I have performed in my company
and that of two other companies.
Company 1) - The result is that some DNS requests are sent to the first IP
address and some are sent to the second IP address, even though both DNS
servers are available.
Company 2) - The result is that DNS requests are sent to the first IP address
and are only sent to the second IP address, if the first is down.
Company 3) - The result is that DNS requests are sent to the second IP address
and are only sent to the first IP address, if the second is down.
Can anybody explain why there are differing results in different BIND
environments please?
Also, if there is a way of configuring BIND to always work the way it's been
observed for company 2), please could someone let me know.
Many thanks in advance.
Richard Thomas.
