"The domain namespace is organised in a similar structure to the UNIX filename space. You start at the top of the tree at the root.
Immediately below the root at the Top Level Domains. These consist of country specific ones and seven generic Top Level
Domains or gTLDs."
"Below these domains your have the second level domain names. These domain names are usually "delegated" by the administrators
of the relevant TLD which means that someone else is responsible for administering that part of the name space (eg the
administrators of .ie delegated the domain linux.ie to the Irish Linux Users Group, which means that ILUG are now responsible for
administering the domain in any way they see fit. without reference to the administrators of .ie)."
"Once a domain is delegated, the administrators of the domain are responsible for making changes within that domain."
