EPP stands for Extensible Provisioning Protocol. It is a protocol that is used in the domain name industry to automate the management of domain names and domain registration services. EPP enables domain registrars, resellers, and registries to communicate with each other and perform various domain operations such as registering new domain names, transferring domain names between registrars, renewing existing domain registrations, and updating domain contact information.
EPP works on a client-server model, where the client is usually a domain registrar or reseller, and the server is the registry or registrar responsible for managing the domain names. The communication between the client and server takes place over a secure network connection, typically using the Transmission Control Protocol (TCP) and Secure Sockets Layer (SSL) or Transport Layer Security (TLS) encryption.
The EPP protocol is extensible, meaning that it allows for the addition of new domain-specific commands or extensions to support additional functionalities. This flexibility enables domain registrars and registries to implement custom features and services while adhering to the standard EPP specifications.
EPP was initially developed by the Internet Engineering Task Force (IETF) and has become the de facto standard for domain name provisioning and management. It has simplified and streamlined the domain registration process by automating many manual tasks, reducing administrative overhead, and enhancing the overall efficiency of domain operations.
