What is an RIR?
A Regional Internet Registry (RIR) manages
the allocation and registration of Internet

What is an IP Address?
Unique identifier for a computer or device
on a TCP/IP network that facilitates moving
data between networks
Every device directly connected to the Internet
needs a unique IP address

Maps host name to unique IP address
A means of storing and retrieving information
about hostnames and IP addresses in a distributed

Regional Internet Registries (RIRs) manage the allocation and registration of Internet number resources such as IP addresses and autonomous system numbers. They operate as not-for-profit organizations providing core services like resource distribution, maintaining directories, and facilitating policy development. The Number Resource Organization (NRO) coordinates RIR activities, promotes bottom-up policy processes, and supports the multi-stakeholder model in Internet governance. Additionally, the Internet Corporation for Assigned Names and Numbers (ICANN) plays a key role in global internet coordination. Explore more at the provided links.
