Overview of this book

The Domain Name System is one of the foundations of the internet. It is the system that allows the translation of human-readable domain names into machines-readable IP addresses and the reverse translation of IP addresses into domain names. This book describes the basic DNS protocol and its extensions; DNS delegation and registration, including for reverse domains; using DNS servers in networks that are not connected to the internet; and using DNS servers on firewall machines. Many detailed examples are used throughout the book to show perform various configuration and administration tasks.

8.2 Regional Internet Registry (RIR)

As we have already mentioned, the world is geographically divided into five regions. Five RIRs are currently established:

  • RIPE NCC (Réseaux IP Européens Network Coordination Centre), which administers Europe and the Middle East. For more details see http://www.ripe.net/.

  • ARIN (American Registry for Internet Numbers), which administers North America and Africa south of the Equator. For more details see http://www.arin.net/.

  • APNIC (Asia-Pacific Network Information Centre), which administers the Asia-Pacific region. For more details see http://www.apnic.net/.

  • LACNIC (Latin America and Caribbean Network Information Centre), which administers Latin America and the Caribbean. For more details see http://www.lacnic.net/.

  • AfriNIC (Africa Network Information Centre) for Africa and the Indian Ocean region, see http://www.afrinic.net/.
