No Contracts
A domain name is essentially online real estate. The registration of this domain name provides temporary ownership over that real estate. Domain registrations allow the registrant to “build” on this property (such as example.com) by offering services such as websites, email, and FTP for personal, commercial, or public use.
The domain registration only includes rights to the domain name you purchase (such as example.com) for the period of time you leased the domain registration, usually one to ten years. With this registration you can set the contact information for the domain, change the nameserver delegation, and add glue records.
Domain registrations do not by itself include any other services, such as DNS, email, Secret Registration, etc.
