What Is TLD Name Server?

A TLD (top-level domain) is the highest level of domain names in the root zone of the DNS of the Internet. For all domains in lower levels, it is the last part of the domain name, that is, the label that follows the last dot of a fully qualified domain name. In other words the last part of an Internet domain name that follow the final dot of a fully qualified domain name. For example, in the domain name www.dnsknowledge.com, the top-level domain is com.
