Netstefnumóta

Netstefnumóta is an Icelandic term for network numbering, a framework of policies, standards, and practices for allocating and managing identifiers used in computer networks, including IP addresses (IPv4/IPv6), MAC addresses, DNS names, ASN numbers, and resource registries. It covers addressing, naming, and routing, and governance.

The allocation of IP addresses is coordinated internationally by IANA and distributed by regional registers (RIPE NCC, APNIC, ARIN). DNS is overseen by ICANN and country-code registries like ISNIC for .is domains. National and regional operators implement policies per netstefnumóta to ensure uniqueness, stability, and efficient routing.

In practice, netstefnumóta informs network design, addressing plans, address assignment for devices, subnets, NAT usage, routing policies, and domain name management. It has implications for privacy, security, and network resilience.

History and governance of netstefnumóta trace to the early development of the Internet, with increasing formalization of addressing and naming systems over time. It evolved through widespread adoption of IPv6, tighter coordination among registries, and the establishment of national and regional policies for resource management. In Iceland, national infrastructure relies on RIPE NCC and ISNIC for domain space and IP/resource allocations, illustrating how international standards intersect with country-level administration.
