Hi,

maybe netcat should support ipv6 ("-6" option).

The latest official release on Sourceforge doesn't have it but Debian includes a patch to add it.

There is a more featured and maintained netcat implementation (ncat)
provided by the nmap package. It does support IPv6.

Hmm, would it make sense to deprecate the "netcat" package then--with a hint on
how to get the functionality (by installing nmap)?

There is no shortage of netcats in Guix.

In addition to 'ncat', there is 'netcat-openbsd', and LibreSSL also
includes a 'nc' executable; all of which support IPv6 to my knowledge.

I don't have an opinion on favoring one over the other. But it would be
good to deprecate the unmaintained GNU netcat with something that works.

Debian doesn't seem to be using GNU netcat anymore; their control file
[0] mentions the home page to be [1], and the version is at 1.10, not
that this is very useful.

I wouldn't remove the package since it seems to be still functioning
despite seemingly abandoned.
