You're quite right in thinking that LVS won't do that. > The ipvs does show dns names, but it's a reverse query, not so much > responsible for the allocation of load.

Note however that in most cases this sort of application will be running on an OS which caches the results of DNS queries for a while (depending on config) - the inbuilt resolver in glibc might do this, plus the queried nameservers tend to deliver the same result and many apps use the first result they receive. If you're looking to do something whereby you automatically add/remove hosts as realservers without having to modify the load balancer itself... I'm not aware of one. Sorry! >From a different perspective, this doesn't seem like a very efficient way of handling incoming queries - a lookup for every "hit"? Do you mean every connection, or every single packet?
