Chapter Summary Continued
The Internet Assigned Numbers Authority (IANA) and the Internet Network Information Center (InterNIC) work together to subdivide and issue addresses for Internet clients.
Three classes of addresses (A, B, and C) are available to organizations.
- Class A addresses are for governments worldwide.
- Class B addresses are assigned to medium to large companies and universities.
- Class C addresses are assigned to organizations and individuals who require an IP address, but who do not meet the criteria to have a Class A or B address.
Two other address categories, Class D and Class E, exist. Class D addresses are used for multicasting information. Class E addresses are used for experimentation and research.
