Reseller hosting is a form of web hosting wherein the account owner has the ability to use his/her allotted hard drive space and bandwidth to host websites on behalf of third parties.

The reseller purchases the host's services wholesale and then sells them to his customers for a profit. The certain portion of hard drive and bandwidth is allocated to reseller account.

In order to achieve this the reseller may rent a dedicated server from a hosting company or resell shared hosting services.

If the latter is the case the reseller is simply given the permission to sell a certain amount of disk space and bandwidth to his own customers without renting a server from a web hosting company he signed for a reseller account with.
