IPv6 Reachability of cPanel Server Login Forms

31 Aug 2022

Due to a cookie problem (some browsers/providers randomly switching from IPv6 to IPv4 and back or vice-versa within a short time period) that causes automatic logouts after a short period of time, we have decided to change the IPv6 login forms of our cPanel servers. You can reach the IPv6-only version by adding "six" to the prefix of your server, e. g.:

IPv4-only hostname IPv6-only hostname
cp1.serverclienti.com cp1six.serverclienti.com
cp2.serverclienti.com cp2six.serverclienti.com
....serverclienti.com ...six.serverclienti.com

Currently this is the most practical solution to this problem, short of allowing unsecure session handling.
