That does require a reboot, which I know you are looking to avoid, so you may want to try other methods to remove your address in the running configuration.'All' I need is for the system not to have a global IPv6 address. Then it will not try to connect to other global IPv6 systems which will reject the connection, as the IPv6 rDNS cannot be set, given it is a dynamic IPv6 assigned address from the ISP.

IPV6_AUTOCONF=no Ryan
