'''Extensible Provisioning Protocol (EPP)''' is an [[XML]] based protocol used by the Internet industry, particularly the [[registrar]]s and [[Registry|registries]] in managing domain names (register, renew, modify, delete, transfer) and other elements in a [[SRS|Shared Registry System]] environment. It is the standard protocol used by a majority of [[gTLD]]s and [[ccTLD]]s.<ref>[http://www.uknof.org.uk/uknof5/Brown-EPP/ What is EPP?]</ref> As described by [[RFC]] 3730, EPP can be used in a multiple layered protocol and operating environments with different transport and security requirements. MIME media type application/epp+xml identifies the content of EPP.<ref>[http://tools.ietf.org/html/rfc3730  Extensible Provisioning Protocol (EPP)]</ref>

==EPP Command Categories==

==EPP Command Categories==

A command is initiated by clients. A certain command is processed by a server so that the client who initiated it will receive a response. The three types of EPP commands include:

A command is initiated by clients. A certain command is processed by a server so that the client who initiated it will receive a response. EPP commands include:

# session management commands- establish and end persistent sessions with an EPP server

# '''Session Management Commands'''- establish and end persistent sessions with an EPP server

# query commands-perform read-only object information retrieval operations

# '''Query Commands'''- perform read-only object information retrieval operations

# data transform commands-perform read-write object management operations
