Re: [CentOS] Slow domain resolution problem

Not sure if it is RDNS.

I had similar issues on Fedora, and for me it was to do with IP6.

Konqueror web browser took ages to load a page. IIRC Firefox handled it OK.

Try Googling for 'uninstalling ipv6 linux'

I already tried that. The /etc/sysconfig/network has the IPV6_ENABLE=no. Disabling the ip6 modules is not feasible, as the bonding module depends on it.

Another thing is how many DNS IP addresses do you have in /etc/resolv.conf?

I don't have an ISP DNS, but the address of the internal DNS server, which has all the mappings for our domain.

Thanks for your help, I'll keep on trying :)
