How to disable ubuntu 14.04 ipv6

Posted on November 21, 2014

Hi,

I want to disable ipv6 on my ubuntu 14.04 system. I have tried to put the end of /etc/sysctl.conf file

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1

these three lines and reboot but it can’t take ip address anymore.

How to disable ipv6 from my system?

I actually finished solving the exact same issue right now with a bit of help from a support person.

First of all let me say this, the support (so far) has been AMAZING and need I say FAST.

Once the support person indicated to me that IPV6 was causing the issue, I immediately searched Google and found this lovely thread. If this thread didn’t exist, I’d probably still have an opened ticket, but instead, @kamaln7 's post worked flawlessly.

Thanks once again @kamaln7 for helping the community out. I owe you one.

I was also using the MailGun API to send emails and IPv6 was the reason, it was giving the Gateway Timeout Error.

Error resolved when enabled precedence in /etc/gai.conf:

precedence ::ffff:0:0/96 100
