Maybe I'm not being very imaginative, but how can something from !53 be
considered a DNS response to a query sent to port 53? Can you give some
examples of the sorts of packets that fall into this rather large % of
ill-behaved hosts? Are you sure you're not treating things like icmp port
unreachable as a "!udp/53 src response"?
