Generic top-level domains (gTLDs) are the most common type of domain name, in part because this category includes .com domains – which have more registrations than all of the ccTLDs combined.
Historically, the main gTLDs were .com, .org, .net, .edu, .gov and .mil, but the number of available gTLDs has been expanded with the result that there are now hundreds of available gTLDs including .online, .xyz and .name.
