sure all these may work..but my $0.2 is: why??? the point of having multiple DNS servers is to spread zone info on as wide as possible; they should also contain IDENTICAL information (one master and all the other slaves loading on the master). so for 2 IPs on the same machine is kinda pointless since they'll go down the same way. I'd spread DNS servers as far apart as I can (different computer, different network segment, diffrent country!). so anyway it shouldt matter which dns server gets priority, they should contain the same info! PLUS, all the other nameservers cache yur info already anyway (the client's ISP's name servers WILL HAVE your zone info and WILL STAY on their cache as per your Zone's TTL values...so why bother to cache it..
so anyway i dont know what the original poster wanted to do.....its rare that one has like a hundred zones so why load balance it (if load balancing is the objective)-- just posting my ideas here.. jondz On Wed, 2003-07-02 at 22:41, Pong wrote: > On 2 Jul 2003, Hagibis Fan wrote: > > re: > > > > yeah, NS records do not have preference or weigth values > like that of MX mail records. > and usually, dns clients querying your NS servers will just > do round-robin. knowing that, you can make one of your NS server > preferable (if you have control over them) by: > > a) giving the favorable NS server more IP addresses/aliases and announcing > them too. so if you have two NS servers, giving the favorable one > another 2 IP aliases should increase its round-robin probababilty > from 50% to 75%. increasing the number of aliases is directly > proportional to higher probability. in case of dns clients basing > it on response times, be sure to make the faster NS server favorable. > > b) setting up a udp-proxy in front of your NS servers. then configure it > to always use your favorable NS server and just resorting > to the other ones when the favorable NS server goes down or gets > overloaded. > > know that you can always the bend the rules =) > > pong > > > -- > Philippine Linux Users' Group (PLUG) Mailing List > [EMAIL PROTECTED] (#PLUG @ irc.free.net.ph) > Official Website: http://plug.linux.org.ph > Searchable Archives: http://marc.free.net.ph > . > To leave, go to http://lists.q-linux.com/mailman/listinfo/plug > . > Are you a Linux newbie?
