+* Each IPv4 address assigned to a network interface has an IPv4 netmask
+  tied to it instead of being set for the whole interface.
+  If there is only one IPv4 address specified for a network interface,
+  nothing changes from the user point of view. But, if there is more than
+  one IPv4 address / network interface, the netmask must be specified
+  for each IPv4 address separately. (:github:`68419`)
