Using an extra page as your private entry point or a cookie, as Mike 
suggests, are good approaches since in the scenario you describe 
(your using a dynamically assigned ip address) you want to exclude 
that address only for your current session. It might happen that the 
address you used on one day another user gets on another day and you 
would not want to exclude them necessarily. In order to do that, your 
system must either identify your connections as they come or log each 
of your sessions, in a file or in a database, so later analyses can 
exclude those connections.
