INNlist

INNlist is a system used to manage and distribute lists of Internet Number Resources (INRs). These resources primarily include Internet Protocol (IP) addresses and Autonomous System Numbers (ASNs). The goal of INNlist is to provide a centralized and standardized method for organizations to declare and share information about their acquired INRs. This information is crucial for various internet operations, including routing, network management, and resource allocation.

The INNlist system typically involves a structured format for describing the INR assignments. This format allows for the inclusion of details such as the resource type (e.g., IPv4, IPv6, ASN), the assigned block or number, the organization to which it is assigned, and potentially other relevant metadata like contact information or the date of assignment. The data within INNlist is often made publicly accessible, contributing to the transparency of internet resource distribution.

Organizations that hold INRs, such as Regional Internet Registries (RIRs) or large network operators, contribute to and utilize INNlist. By maintaining and updating these lists, INNlist facilitates better coordination and interoperability across the global internet infrastructure. It helps prevent conflicts, aids in troubleshooting routing issues, and supports the overall stability and efficiency of internet operations. The development and maintenance of INNlist are often undertaken by bodies involved in internet governance and technical coordination.
