RIRs, or Regional Internet Registries, are organizations responsible for the allocation and management of IP address resources within specific regions. Their primary role includes allocating IP addresses to Internet Service Providers (ISPs) and other large organizations, as well as managing WHOIS services that provide information about the registration of IP addresses.

Facilitating internet governance is also part of their responsibilities, often involving coordination with global and regional entities to ensure that policies related to IP address management are upheld.

However, registering domain names is not a service provided by RIRs. Domain name registration falls under the purview of domain registrars, which operate under the auspices of organizations like ICANN (the Internet Corporation for Assigned Names and Numbers) that manage the domain name system (DNS) globally. This distinction is important, as it highlights the different roles that these organizations play in the internet infrastructure; RIRs focus on IP addresses while registrars deal with domain names.
