Linux round Robin DNS
Posted on 2007-11-29
I am confused on Linux DNS Round Robin.
If I have a hostname with several different ips , this seems to work correctly as each time I ping I get a different ip to that same hostname. My guess is that the ttl is set very low for this to work. ( I did not build this)
My confusion is probalby that I am thinkng to windows on this . However, if I do the same setup in Wndows. the client resovler cache will cache the first ip it resolves and then use that until cahce times out. So, this kind of defeats the notion of round robin DNS. I can turn the client cache off but now that increases traffic to DNS server. Also will ignore TTL , unless you play with registry...
Does Linux not have a client resolver and that is why this is not an issue????
