I wonder if the package is still relevant, because it has only one
reverse dependency, which in turn has no reverse dependencies:

$ apt rdepends libnet-ipaddress-perl
libnet-ipaddress-perl
Reverse Depends:
  Depends: libnet-google-safebrowsing2-perl

$ apt rdepends libnet-google-safebrowsing2-perl
libnet-google-safebrowsing2-perl
Reverse Depends:

The same for reverse build-dependencies:

$ grep-dctrl -FBuild-Depends libnet-ipaddress-perl -w -sPackage /var/lib/apt/lists/*Sources
Package: libnet-google-safebrowsing2-perl
$ grep-dctrl -FBuild-Depends libnet-google-safebrowsing2-perl -w -sPackage /var/lib/apt/lists/*Sources


Disregarding Holger's NMUs of both packages, their relevant changelog
entries date back to April 2013.

Maybe they are both candidates for removal?

We might also move it to the Debian Perl Group.
(Team list cc'd, I won't be able to do it in the next few days but
there are plenty of other people :))

Cheers,
