    Is there any particular reason why the packets dropped by my zone
    alarm firewall are now not showing reverse dns lookups in large numbers
    when they did so previously. The ports involved seem to be those for
    well known worms that used to provide the dns lookup for the ip address
    but over the last few weeks or so, the reverse dns column has just gone
    mostly blank! Thanks again for any replies.
