Dear customer,
A Small Business License allows 10 such names
An IP license enables all the domains/subdomains hosted on this IP@ to use the control.
All license options are good for
http://localhost. I'd highly recommend Small Business License as it's the most popular choice among our customers. Out of the 10 names, you can use one or two for the internal dev server ie.
http://intranet while keep the rest for your production servers.
Developer license is a higher license that allows CuteEditor to be integrated into all his applications without additional license required. If Domain license can fit your needs, there is no need to purchase a developer license to cover your development process :)
