I have not had time to investigate deeply, posting here so the info is
not lost. I have already fixed one issue related to perl-data-validate-
ip in 8ec03ed5475ca7919a7d11541ff8cbf33a9ffe67, but it seems there's
several others.

One as CVE recently:

CVE-2021-29424 18:15
The Net::Netmask module before 2.0000 for Perl does not properly
consider extraneous zero characters at the beginning of an IP address
string, which (in some situations) allows attackers to bypass access
control that is based on IP addresses.

Can't find a corresponding package in GNU Guix.

To be continued!
