The top-level domains (TLDs) are managed by registrars under agreement from ICANN (www.icann.org). There are several different types of TLDs:

• gTLD - Generic top-level domains (.com,.net,.org...)- Anybody can register these domains
• ccTLD - Country code top-level domains (.uk,.us,.ly,.cc) - These domains normally have restrictions on their use, for example, only companies that operate in these countries may register them (.uk does not have this restriction, but.ie, Ireland, does)
• sTLD - Sponsored top-level domains (.coop,.museum,.jobs) - These domains are for certain uses only. There are strict rules which must be met in order to register one of these domains.
