Hello! Can i set up two DNS (aaa.com bbb.com) in the same computer using one IP? If yes, how to do it? Thanks for your help! Martin

Well, first I presume your DNS server is the SOA for ALL of the domains you desire to host. If you've already configured aaa.com in your own DNS server, you would just create an additional zone named bbb.com and all of the associated records for that zone, i.e. www, mail, ftp, etc. Now that you have multiple domains pointing to the same IP, you'd need host header redirection to route www.aaa.com and www.bbb.com to different web sites.
