Hi, I am planning on starting an adsense business and I already have a reliable place to register domains, but I need a hosting service that works well for my type of business. Adsense business's require a lot of domains, and I need the ability to add/remove/edit the domains easily under one account. (Including editing the files of each site.) Therefore, unlike a traditional hosting account with a single primary domain, I need a hosting service that can offer the same services but for multiple domains. Mysql compatibility and FTP access are a must.
Rent a VPS Server and use domain dashboard to create bulk accounts on your VPS very fast... On a VPS you have unlimited add on domains
Have a look at web hosting section at DP marketplace. There may be some companies offering unlimited domains under one account.
