Slow browsing

If you are suffering from incredibly slow browsing, but nslookup returns DNS records in a snap then this might help!
Basically completely disable IPv6

$ chkconfig ip6tables off
$ nano /etc/modprobe.d/blacklist.conf

Add "blacklist ipv6" at the top

$ nano /etc/modprobe.d/dist.conf 

Add "alias ipv6 /bin/true" at the top
