I've got very short and attractive domain. So I am looking for a script that enable me to sell subdomains in it. But I don't want to sell aliases, but 'real' domains that can be assigned to buyer's server and full-management. For example: I've got my.tv and on my site is possible to buy john.my.tv Someone buys this domain and he can do with it anything he want (the same as he buys john4564.com). Maybe someone knows such script. I hope I was understandable.
Well there won't any no script available for it.This will need total DNS management and other stuffs. You have to hire bunch of programmers to code it.
I think it is against the rules of ICANN to sell this type of things in domain. Yet just make sure you read all the rules first.
