Subject: [PATCH] nixos/networking: Switch to home.arpa as an example for the
 domain

The special-use domain "home.arpa." is designated for non-unique use in
residential home networks [0] and registered as such [1]. Therefore it
is more appropriate than "home." which could cause conflicts or result
in queries that leak out and reach the root name servers.
