Thanks for reading along.... :) We have a large FreeBSD server farm... around 160 boxes, pushing about 400 megabits/second. We also have ONE dns server pushing TWO megabits of DNS requests per second :) The way DNS works for windows boxes (our primary clients connecting to our network) is that when InterNic reports to the users DNS server the IP address they are resolving, most times they only try connecting to NS1.FLYINGCROC.COM. If this server is down, the time is takes to go look at NS2.FLYINGCROC.COM can take sometimes up to 30 seconds. Hence, the InterNic method of primary and secondary name service is not acceptable for our network. We need to load balance and set redundancy locally. So, if we wanted three servers with identical bind-8 configurations running and setting up these servers in round robin or some other load balancing mechanism, what is the best method? We use bind itself to delegate requests in round robin to webservers themselves, but this solution doesn't work for the DNS server when the IP is hardcoded into the InterNic record itself! Suggestions on setting up three DNS servers in a load balancing system with a network appliance would be appreciated! We've looked at Local Director and it doesn't look like this solution is quite practical. Anyone else have any success? .. andy -------------------------------------------------------------------------- Andrew N.
