How do i > configure it? DNS round robin is not about redundancy, the only thing you could have that way is a kind of load balancing (not the most sophisticated way, though). Whenever one of the servers fails, around half of the requests still goes there and then times out/gets conn refused or whatever the problem is. Prioritizing is not easily possible. Probably it helps if you add one of the IPs more often to the set, but I never tried that and did not read the docs on this topic, so before breaking your zone first read the specs, if this works! For serious redundancy with failover and/or load balancing with a good leveling you should consider getting a load balancer (be it hardware or software), better two so you don't have the single point of failure there :-) - Oliver -- | Oliver Brandmueller | Offenbacher Str. 1 | Germany D-14197 Berlin | | Fon +49-172-3130856 | Fax +49-172-3145027 | WWW: http://the.addict.de/ | | Ich bin das Internet.
