The standard requirment is that there are several DISTINCT name servers, for reliability reasons. Having several name servers with the same IP address completely defeats the point. So, no, Zonecheck is right.

Also the idea to "direct more load to the IP address listed 3 times" is probably wrong. The most common DNS resolver, BIND, remembers the fastest name server for a zone and only queries it. It does not distribute according to the number of occurrences.

The standard requirement is only that more than one name server is provided for a zone.

A configuration such as

emsv.co.uk.
a.tport-qrp.ns.emsv.co.uk. 84.234.24.63
b.tport-tcp.ns.emsv.co.uk. 78.105.8.58
d.tport-qrp.ns.emsv.co.uk. 84.234.24.63
c.tport-qrp.ns.emsv.co.uk. 84.234.24.63

is entirely legal ( the purpose is to direct more load to the IP address listed 3 times ).

A warning might be appropriate.

George Barwood
