How To Disable IPv6 In Ubuntu 10.04 Lucid Lynx

How To Disable IPv6 In Ubuntu 10.04 Lucid Lynx.

You may be interested in disabling IPv6 if you use VPN and BitTorrent because there is a security problem as discussed in the thread Huge Security Flaw Makes VPNs Useless for BitTorrent in the Privacy Software subforum.

When no ipv6 routers are present, its automatically disabled and therefore this is not necessary anymore, also you can block ipv6 via firewall.

 

And, you can block it in Firefox!

Thats right, if one opens up network tools in Ubuntu, they will find ipv6 with an ignore tab.

 

In Fedora 13 I edited the /etc/modprobe.d/blacklist.conf file and added the following entries:
#blacklist ipv6
blacklist ipv6

Reboot and then check with:
ip a | grep inet6

no output means ipv6 is successfully blocked
