Adcenter IP list needed

Dear black hat friends!

I've only foud the Google bots ip's. Any chance you know where i can find adcenter ip's?

Any help will be much appreciated

Thanks,
The dude

Anyone please ?

I also need this. Maybe someone could put me in the right direction, on how can I find them? I don;t expect someone to do a research for me and just hand them to me. Thanks a lot!
