       This tool provides a convenient command-line wrapper around the getnameinfo(3) resolver function. It will
       perform a single reverse lookup to convert an address and port number into its host and service names.
       This is mainly useful when debugging names resolution problems, because it allows inspection of the
       getnameinfo(3) behaviour itself, outside of any real program that is trying to use it.

       Upstream this script is known as "getnameinfo", but was renamed on Debian.

       --address, -A ADDR
               Numerical form of address to look up. If not supplied, will use the first positional argument.

       --port, -P PORT
               Port number to look up. If not supplied, will use the second positional argument.

       --dgram Sets the "NI_DGRAM" flag; looks up a "SOCK_DGRAM" (udp) port allocation rather than "SOCK_STREAM"
               (tcp).

       --help  Display a help summary and exit
