.ARPA - Internet Infrastructure Domains
Online Domain Name Extension Directory
Meaning: Address and Routing Parameter Area.
Notes: "The .arpa domain is the Address and Routing Parameter Area domain and is designated to be used exclusively for Internet-infrastructure purposes. It is administered by the IANA in cooperation with the Internet technical community under the guidance of the Internet Architecture Board. For the management guidelines and operational requirements of the .arpa domain, see RFC 3172 (BCP 52). (Quote from iana.org/arpa-dom/)
Second level extensions: Each domain handles a different type of Internet addressing/routing.
e164.arpa - ENUM lookup mapping telephone numbers into DNS
in-addr.arpa - reverse DNS lookup for IPv4 addresses (the 32-bit IP addresses currently used by web servers, etc.)
ip6.arpa - reverse DNS lookup for IPv6 addresses (the new 128-bit IP addressing that will eventually replace IPv4)
uri.arpa - for dynamic discovery of URI addressing schemes (handles URI's i.e. http:// ftp:// , mailto: etc)
urn.arpa - for dynamic discovery of URN addressing schemes (handles the uniform resource name type of URI)
The .tel domain has apparently been proposed as an alternative to the use of e164.arpa
...and the new IP6 will make it possible for there to be enough IP addresses to go around so that even your toilet and refrigerator can have an IP address.
