TCP port 1526 is commonly used as an alternative port for Oracle Database Listener services. The Oracle Listener facilitates incoming client connections and routing to the database, playing a fundamental role in Oracle environments. Administrators might configure port 1526 instead of the default 1521 for security or network segmentation reasons.

A port number is not a service. Anything may listen on 1526 — what you actually met is decided by the host, not the registry. If a service is missing here, it belongs in the registry.
