Registry Registrar Protocol

Registry Registrar Protocol (RRP) is a network protocol primarily used to facilitate communication between domain name registrars and a registry. It allows registrars to perform domain management operations such as registration, deletion, updating, and querying of domain names held by the registry. RRP streamlines the domain provisioning process in top-level domain management systems, serving as a key component in early domain registration services before the advent of newer protocols like EPP.

Sphinx API

Port 9306 is commonly used by Sphinx Search, a popular open-source full-text search server, via its native binary protocol. This port facilitates communication between client applications and the Sphinx server for efficient, high-performance search queries across large datasets. The native API provides optimized indexing and retrieval, allowing developers to build scalable search features within websites or applications.

Citadel Groupware

Port 504 is primarily used by Citadel groupware, a collaborative client-server platform offering email, calendar, contacts, bulletin boards, and more. This port facilitates dedicated Citadel protocol communications between specialized clients and the Citadel server, enabling multiservice access within the unified groupware environment. Both TCP and UDP are supported for flexible and reliable data transfer, underpinning internal messaging, directory access, and real-time collaboration functions.

NetNews Service

Port 532, designated as NetNews, was historically used for distributing network news within USENET and other news delivery systems. While largely obsolete for public services in the modern internet, it exemplifies early distributed communication protocols that formed the backbone of sharing discussions before the widespread adoption of web-based forums and social media.

Commerce Services

**Port 542** is associated with commerce and transaction applications, facilitating data exchange in online business frameworks. It traditionally supports services that enable secure and managed financial transactions, order processing, and related activities within e-commerce and business-to-business transaction environments.

SphinxQL

SphinxQL is a SQL-like query language used by the Sphinx search server to efficiently retrieve indexed data. It enables developers to perform complex full-text searches and data manipulations, similar to interacting with a traditional relational database. Typically communicating over port 9312, SphinxQL offers a robust solution for integrating scalable, high-performance full-text search capabilities into applications.
