The primary function of the Internet Assigned Numbers Authority (IANA) is indeed to assign Internet Protocol (IP) addresses. IANA is responsible for coordinating some of the fundamental aspects of the internet's functionality, which includes the allocation of IP addresses to various regional and local internet registries. This allocation process ensures that every device connected to the internet has a unique address, allowing it to communicate effectively with other devices.

Furthermore, IANA manages the global IP address space and maintains the databases that hold information related to the assignment of IP addresses. By doing so, it plays a crucial role in ensuring that the structure and organization of the internet remain stable and reliable.

To provide additional context, while managing domain name registrations may be seen as an important internet function, this is typically handled by different organizations such as domain registrars and the Domain Name System (DNS). Regulating internet service providers and controlling internet traffic fall under different entities and functions that focus on governance and infrastructure rather than the direct assignment of numerical identifiers necessary for device connectivity.
