is it possible to put false information on the whois registry (admin, billing, etc) for your domain to keep anonymity, yet still have the correct billing address at dreamhost so you can renew/pay etc?
Do a quick search on this here and you’ll see several threads.
Short answer: you can put whatever you want in your whois, but if you put false data in and it comes up for some reason, you can lose your domain because of the violation.
