Comment 4 for bug 1965942

My understanding was that the limits for directly reachable computers in IPv4 is called "netmask" and in IPv6 the equivalent is called "prefix".

gnome-comtrol-center 1:3.36.5-0ubuntu3 on Ubuntu focal correctly shows these different labels for manual settings in IPv4 and IPv6.

In my opinion the only thing to be done for this bug report is adding "prefix" to the documentation in https://help.ubuntu.com/lts/ubuntu-help/net-fixed-ip-address.html.en

Instead of

Type in the IP Address and Gateway, as well as the appropriate Netmask.

it has to be something like

Type in the IP Address and Gateway, as well as the appropriate Netmask (for IPv4) respectively Prefix (for IPv6).
