IPpõhine

IPpõhine is an Estonian term meaning "IP-based." It describes approaches, architectures, or policies that rely primarily on Internet Protocol addresses and routing data as the central basis for identification, access, and decision making in a networked environment.

In practice, IPpõhine can be used in several domains: internet service provisioning and traffic management where customer sessions are associated with IP addresses or IP ranges; access control and security where rules are applied to IP addresses or subnets; content delivery and geolocation where requests are routed or served based on the request's IP address; and billing or usage tracking that attributes activity to IP origins. The concept emphasizes using IP information as the primary input for operational decisions.

Advantages of IPpõhine include scalability, simplicity, and fast decision making without requiring user credentials. Limitations include dependence on IP address stability, privacy concerns, and accuracy issues due to proxies, Network Address Translation (NAT), dynamic addresses, and shared networks; while IPv6 adoption improves some aspects, IP-based methods can still be affected by these factors.

Related concepts include IP address management, geolocation by IP, NAT, firewall rules based on IP, and CIDR notation. The term is primarily used in Estonian IT and telecommunications contexts, but the underlying concept—that operations can be based on IP addresses—occurs in many languages and regions.
