Load-balancers are used for redundancy as well as performance management. In the case of DNS, one way it might be used is to shunt client requests to the servers that are up, thus side-stepping client-side resolve timeouts.

Is that the case? At what point does this occur? -----Original Message----- From: bind-users-bounces+jlightner=water....@lists.isc.org [mailto:bind-users-bounces+jlightner=water....@lists.isc.org] On Behalf Of Alan Clegg Sent: Monday, April 05, 2010 10:58 AM To: bind-users@lists.isc.org Subject: Re: Load Balancer for DNS -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 On 4/5/2010 2:06 AM, sasa sasa wrote: > Hello everyone, > > Any one used any load balancer for DNSs? any recommendation? it's 2 > caching-only DNSs, and I'd like to make a load balance between them > using software. I would recommend that before adding "load balancers" that you consider the problem that you are actually attempting to solve. For the cost of a "load balancing solution" you might be able to deploy more caching servers that would probably work better in the long run..
