The History of Domains
The First Global TLDs
The first seven gTLDs to be created were .com, .edu, .gov, .net, .org, .int, and .mil. The .com, .net, and .org extensions are for general use while the other four have limited use restrictions.
New Top Level Domains
Because the .com, .net, and .org began filling up so quickly, seven more TLDs were authorized as gTLDs. They are .biz, .name, .info, .pro, .aero, .coop, and .museum. Of these New gTLDs as they are often referred to, .biz, .name, .info, and .pro are available to the general public. The generic top level domains may be registered regardless of geographical location, which is why many say gTLD stands for global top level domains. The names may be registered globally. Country Code top level domains may have some regional restrictions.
