How-To: Disable IPV6 to speed up Internet.

[xshady87]

I'm a bit confused. Where exactly do I go about typing this? In the terminal? Because I tried it there, and after the second line it said "directory not found".

If you're having problems in Synaptic or Firefox, if you're a newbie like me, here's the process at it's most basic:

ipv6 is a protocol not handled by many routers. It's new and will be needed someday (which means a long time from now (like years) you're gonna have to buy a new one. In the meantime, config linux not to use it by:

1. Open a Terminal Window
2. Type sudo gedit /etc/modprobe.d/bad_list/
3. In the gedit window, type: alias net-pf-10 off
4. Save the file and reboot.

To make sure you no longer have ipv6 running, open a terminal window and type:
ip a | grep inet6

Many thanks to mhael for this process!

this is what i am getting before and after creating the file....

ip a | grep inet6
inet6 ::1/128 scope host
inet6 fe80::212:f0ff:fe24:202d/64 scope link

any clues..... ???

Hi
neoflight,
I had to go into Firefox as well.Open a new tab and type "about:config". Then scroll down to "network.dns.disableIPv6"...if it reads "true", leave it. I f it reads "false", double-click on it to make it read "true".
Then try the test again: ip a | grep inet6

Thanks to mhael again, you made it very clear for a newbee like me to follow.

Yagisan, well said. I would add that ipv6 was considered necessary until the widespread use of NAT routing made it less so. Now, due to NAT routing, everyone in a household can have their own private ip behind the NAT router, which only requires one ip address from your ISP. Even some ISPs are now using NAT routing for their customers. This has taken a lot of the pressure off in needing immediate implimentation of ipv6.

So, maybe a solution would be during the install of Ubuntu, ask whether you want/need ipv6 enabled, and take the appropriate action...

Then there would only need to be a HOW TO on "enabling ipv6" when it is needed...

There's an easy way: instead of changing aliases file, create fie named bad_list in /etc/modprobe.d containing this line:

alias net-pf-10 off

Now reboot and voila, no IPv6 on your system!

This method will work even if /etc/modprobe.d/aliases get replaced at some update.

Thanks a lot for your solution. just what a newbe like me needed. after a upgrade to the latest dapper my internet dident work at all,even not after trying to disable ipv6 in firefox.
But now i am writing from my ubuntu box.

Outstanding suggestion! I did this on both my Ubuntu boxes and it worked like a charm. I had actually done this in Windows a long time ago, but never thougt about it in Linux until this thread. Thank you all. Web pages are poppin'.

It works well and definetly speeds up the 'net all around, but their still seems to be a delay. In windows when I go to a URL it loads instantly in Ubuntu it takes a second or two until looks for the server.

My sisters laptop uses a wireless connection and webpages load instantly with windows.
