Some general help with DNS
A round robin lets you load balance by pointing the same host name to multiple servers in DNS.Â As long as round robin service is enabled in the DNS server, incoming requests will be spread among the servers.
- In the DNSÂ Mgmt applicationÂ on your DNS server, right click the server name in the tree in the leftÂ pane, select Properties, select the Advanced tab, ensure that â€˜Enable round robinâ€™ is selected.
- AddÂ HOST(A) records in the appropriate forward lookup zone, pointing to the servers to be covered.
- If you want a little poor-man's fault tolerance, ensure that the TTL of each record is set to a short period of time, i.e. 15 seconds.Â This ensures that if one of the servers fails, repeated attempts to connect will soon hit another server.
