1. What is IANA?!

2. Internet Assigned Numbers
Authority!
+ Responsible for global, unique Internet
identifier systems
+ One of the oldest Internet institutions, its
role dates back to the 1970s
+ “IANA” now refers to a series of functions
performed to coordinate unique Internet
identifier systems
+ Today, ICANN performs the IANA functions

Protocol
Assignments
Number
Resources
Root
Zone
Management
(Top-­‐
level
Domain
Names)

4. Root Zone Management !
(Top-level Domain Names)!
+ Domain Names allow Internet users to type
in “iana.org” instead of a series of numbers
+ ICANN’s IANA department operates and
maintains a number of key aspects of DNS
+ Root zone file change requests for ccTLDs
and gTLDs

5. Number Resources!
+ Each device connected to Internet has
unique identifier called IP Address.
+ Examples:
+ 208.77.188.102
+ 2620:0:2d0:5:218::78e0
+ Large numbers of computers are grouped
into Autonomous Systems.
+ Large blocks of addresses allocated to
Regional Internet Registries (RIRs) for
distribution.

+ Operators and managers of ccTLDs and gTLDs!
+ Governments!
+ Internet user community!
