Since 1998 ICANN, a non-profit organisation, has assumed this responsibility from the US government.

The cc TLDs are delegated to the individual countries for administration purposes.

Figure 1.0 above shows how any authority may in turn delegate to lower levels in the hierarchy, in other words it may delegate anything for which it is authoritative.

Finally, since 2011 the TLD policy is essentially unrestricted, if you pay enough money and adopt the operating procedures laid down anyone can register a sponsored TLD.

The Domain Name System uses a tree (or hierarchical) name structure.With 100 of millions of hosts and billions of web pages it is an impossible task - it's also pretty daunting even with just a handful of hosts and resources.To solve this problem the concept of Name Servers was created in the mid 70's to enable certain attributes (properties) of a named resource to be maintained in a known location - the Name Server.Thus, today you can register or (as long as they are available).The old delegation models are still valid and you still domains such as ca as well as numerous other examples of the multi-layer delegation model.Countries with more centralized governments, like the UK, Brazil and Spain and others, have opted for functional segmentation in their delegation models, for example, = company, = academic etc..
