- N-1-1-040.25 The IANA Story, Jon Postel*, <postel@isi.edu>
-
-
- The Internet Assigned Numbers Authority (IANA) provides for the
- assignment of numbers, keywords, and other protocol parameters for the
- Internet community.
-
- For example, the assignment of network numbers, protocol numbers, port
- numbers, and MIB numbers are the responsibility of the IANA.
-
- The Internet Activities Board (IAB) has the responsibility for the
- management of the Internet including its address spaces. The IAB has
- delegated the management of the Internet address spaces to the IANA.
-
- The IANA is located at USC's Information Sciences Institute in Marina
- del Rey, California, and is staffed by Joyce K. Reynolds and Jon Postel.
-
- The assignment and recording of network numbers is a substantial part
- of the activity and this has been identified as the Internet Registry.
- The support of the Internet Registry is currently delegated to the
- Network Information Center. For the assignment of an Internet network
- number (an IP address) please contact "Hostmaster@NIC.DDN.MIL".
-
- The following is a list of the types of numbers, keywords and other
- parameters currently registered or recorded directly by the IANA:
-
- Version Numbers
- Protocol Numbers
- Port Numbers
- Unix Ports
- Internet Multicast Addresses
- IANA Ethernet Address Block
- IP Type of Service Parameters
- IP Time to Live Parameter
- Domain System Parameters
- BOOTP Parameters
- Network Management Parameters
- ARPANET and MILNET Logical Addresses
- ARPANET and MILNET Link Numbers
- ARPANET and MILNET X.25 Address Mappings
- IEEE 802 Numbers of Interest
- ETHERNET Numbers of Interest
- ETHERNET Vendor Address Components
- ETHERNET Multicast Addresses
- XNS Protocol Types
- PRONET 80 Type Numbers
- Address Resolution Protocol Parameters
- Reverse Address Resolution Protocol Parameters
- Dynamic Reverse Address Resolution Protocol Parameters
- X.25 Type Numbers
- Public Data Network Numbers
- Telnet Options
- Mail Encryption Types
- Machine Names
- System Names
- Protocol and Service Names
- Terminal Type Names
-
- The IANA records the assignment of these and other numbers and
- occasionally publishes lists of the currently assigned numbers and
- parameters in an RFC titled "Assigned Numbers" (most recently as
- RFC-1060).
-
- A common request to the IANA is for the assignment of an enterprise or
- "company private" management information base (mib) number.
-
- A more interesting case is a request to assign a port number for a new
- application or service based on UDP or TCP. In these cases, there is
- often some discussion to understand the protocol aspects of the use of
- the port. Normally, a two-page description of the application
- (focusing on the protocol aspects) is required before a port number is
- assigned.
-
- Other types of assignments are less frequent. It is always helpful
- when a request is accompanied by a description of the proposed use of
- the parameter to be assigned.
-
- To contact the IANA for information or to request a number, keyword or
- parameter assignment send an electronic mail message to "iana@isi.edu".
