Explanation:

• Internet Corporation for Assigned Names and Numbers (ICANN). ICANN coordinates these unique identifiers across the world. Without that coordination we wouldn't have one global Internet.
• ICANN was formed in 1998. It is a not-for-profit partnership of people from all over the world dedicated to keeping the Internet secure, stable and interoperable. It promotes competition and develops policy on the Internet’s unique identifiers.
• ICANN doesn’t control content on the Internet. It cannot stop spam and it doesn’t deal with access to the Internet.
• But through its coordination role of the Internet’s naming system, it does have an important impact on the expansion and evolution of the Internet.
