UDP port 53 gets queried on several of the firewalls that I maintain (and that do not provide any domain name services) from netblocks that are owned by microsoft and realmedia (mostly). None of the machines behind these firewalls are allowed any external DNS directly. The queries are rather massive (thousands per week). Searches on google did not turn up anything and I don't remember seeing anything on the lists either (though I migh have prematurely deleted something relevant because of the noise ;^)
Search for BigIP, check the Incidents mailing list archives. These are (probably) global load-balancer devices, designed to help the site pick which server(s) to handle your queries.
