Sometime you just need to disable IPv6 protocol. In some case, you do not need it at all or it may increase browsing speed.
Linux has Internet Protocol Version 6 (IPv6) enabled by default, almost all distro enable it.
Open your modprob.conf file (Red Hat and friends) and add following line:
# vi /etc/modprobe.conf
Add following line:
alias net-pf-10 off
Save and close the file. Reboot the system.
If you are using Debian/Ubuntu linux (thanks to beranger), open file /etc/modprobe.d/aliases
# vi /etc/modprobe.d/aliases
Find the line:
alias net-pf-10 ipv6Replace to
alias net-pf-10 off
alias ipv6 off
Save and reboot the system. IPv6 support should now be disabled and it did improve my DNS performance. Also you can install DNS proxy - to improve DNS performance and squid caching server.
