The easiest and most robust way is to add a DNS zone for dyn.com to your DNS server. This will cause it to be unable to serve any DNS records for that domain.
If you want to do this at a firewall level, the easiest way is to add routes for the IP block belonging to dyn.com, pointing them to someplace useless, like the loopback interface, or NULL if that is supported by your route command. -wes On Thu, Sep 8, 2011 at 2:20 AM, Keith Lofstrom <[email protected]> wrote: > I hope this makes it out.
