RE: http://www.worm.com/default.ida? requests

["Marc Maiffret" <marc () eeye com>]

Some web cacheing systems and sniffers take the Host: header from a HTTP
request and put that as the DNS name for the incoming IP address. and whats
in the codered host header? worm.com. So some things display worm.com as the
incoming/outgoing (depending on what packet your viewing) request.
