ipv6 still won't go away

I know this seems like a beaten old topic, but i just can't disable ipv6 on my laptop. it's important to me, as i am frequently using wifi adhoc iphone tethering and ipv6 just doesnt work right with this method. this results in painfully slow dns lookups. the only place i was ever able to disable ipv6 and keep it disabled is in firefox. along with caching, it makes lookups blazing fast in ff.

i've tried all possible methods from blacklisting the module ipv6 in rc.conf to the modprobe.conf method in the wiki. none work, the ipv6 module is always loaded. if i tried to rmmod it, i get an error that the module is in use.

????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????

Re: ipv6 still won't go away

Is another module loading it?  What is the output of:

$ lsmod |grep ipv6

and

$ lsmod |grep net-pf-10

Re: ipv6 still won't go away

In my case X is using ipv6.

sudo lsof -i | grep -i ipv6

returns:

X         3366  root    1u  IPv6    7760      0t0  TCP *:x11 (LISTEN)

You need to install lsof for the command to work. Probably disabling the ipv6 support in Xorg and recompiling it will enable you to unload the ipv6 module, though i am no expert.
