Question

How to disable IPv6 addresses on a Plesk server?

Answer

In order to disable IPv6, the following steps should be performed:

  1. Go to Tools & Settings > IP Addresses > 2001:db8:f61:a1ff:0:0:0:80 > the Sites column. If there are sites hosted on IPv6, go to Domains > example.com > Web Hosting Access and set the field IPv6 address to None:

  2. Log in to the server via SSH and add the following lines to /etc/sysctl.conf :

    # grep ipv6 /etc/sysctl.conf
    net.ipv6.conf.all.disable_ipv6=1
    net.ipv6.conf.default.disable_ipv6=1

  3. Apply the settings from the /etc/sysctl.conf via the following command:

    # sysctl -p

  4. Remove IPv6 addresses from the Plesk

    Note: It can be done either manually or by pressing the Reread IPs button in Tools & Settings > IP Addresses

    IPv6 is not shown on "Web Hosting Access for domain.com". Only ipv4.

    I can not delete the ipv6 from the server, because plesk says it is in use by "domain.com".

    That means I can not remote the ipv6 from a domain.
