          By default, PostgreSQL will order INETs with shorter (larger) prefix lengths ahead of those with longer
          (smaller) masks. This makes no sense when ordering IPs, which should be ordered solely by family and host
          address. We can use HOST() to extract just the host portion of the address (ignoring its mask), but we must
          then re-cast this value to INET() so that records will be ordered properly. We are essentially re-casting each
          IP address as a /32 or /128.
