The Extensible Provisioning Protocol (EPP) is a flexible protocol designed for allocating objects within registries over the Internet.

The motivation for the creation of EPP was to create a robust and flexible protocol that could provide communication between domain name registries and domain name registrars. These transactions are required whenever a domain name is registered or renewed. Prior to its introduction, registries had no uniform approach, and many different proprietary interfaces existed. A domain name registry, also called Network Information Centre (NIC), is part of the Domain Name System (DNS) of the Internet which converts domain names to IP addresses. ... A domain name registrar is a company accredited, either by the Internet Corporation for Assigned Names and Numbers (ICANN), or by a national ccTLD authority or both, to register Internet domain names . ... The term domain name has multiple related meanings: A name that identifies a computer or computers on the internet. ...

While its use for domain names was the initial driver, the protocol is designed to be usable for any kind of ordering and fulfilment system.

The EPP protocol is based on XML - a structured, text-based format. The underlying network transport is not fixed, although the only currently specified method is over TCP. The protocol has been designed with the flexibility to allow it to use other transports such as BEEP, SMTP, or SOAP. The Extensible Markup Language (XML) is a general-purpose markup language. ... The Transmission Control Protocol (TCP) is one of the core protocols of the Internet protocol suite, often simply referred to as TCP/IP. Using TCP, applications on networked hosts can create connections to one another, over which they can exchange streams of data using Stream Sockets. ... In computer networking, BEEP (Blocks Extensible Exchange Protocol) is a framework for creating network application protocols. ... Simple Mail Transfer Protocol (SMTP) is the de facto standard for email transmission across the Internet. ... This article is about the computer protocol. ...

The protocol is the result of the IETF Provisioning Registry (provreg) working group, and was finalised in 2004. The Internet Engineering Task Force (IETF) is charged with developing and promoting Internet standards. ... Wikipedia does not have an article with this exact name. ... shelby was here 2004 (MMIV) was a leap year starting on Thursday of the Gregorian calendar. ...

The protocol has been adopted by a number of domain name registries, such as .info, .org, .aero, .mobi, .ag, .au, .br, .bz, .eu, .gi, .hn, .in, .mn, .pl, .sc and .vc, as well as ENUM registries such as those operating the +43 and +41 country codes. .info is a generic top-level domain intended for informative websites, although its use is not restricted. ... .org (organization) is a generic top-level domain (gTLD) used in the Internets Domain Name System. ... .aero is a generic top-level domain (gTLD) used on the Internets Domain Name System. ... .mobi (also known as DotMobi) is a top-level domain approved by ICANN and managed by the mTLD global registry dedicated to delivering the Internet to mobile devices via the Mobile Web. ... .ag is the Internet country code top-level domain (ccTLD) for Antigua and Barbuda. ... This article covers the top-level domain name. ... .br is the Internet country code top-level domain (ccTLD) for Brazil. ... .bz is the Internet country code top-level domain (ccTLD) for Belize. ... .gi is the country code top-level domain (ccTLD) for Gibraltar. ... .hn is the Internet country code top-level domain (ccTLD) for Honduras. ... .in is the Internet country code top-level domain (ccTLD) for India. ... .mn is the Internet country code top-level domain ( ccTLD) for Mongolia. ... .pl is the Internet country code top-level domain (ccTLD) for Poland, administered by NASK, Polish research and development organization. ... .sc is the Internet country code top-level domain ( ccTLD) for Seychelles. ... .vc is the Internet country code top-level domain ( ccTLD) for Saint Vincent and the Grenadines. ... -1...

EPP "codes" or "keys" are also required in the transfer of generic top-level domain names between registrars (.com, .net, .org, .biz, .info). .com and .net domain names only began requiring the EPP key from fourth quarter 2006. For dot-com companies, see dot-com company. ... .net is a generic top-level domain (gTLD) used on the Internets Domain Name System. ... .org (organization) is a generic top-level domain (gTLD) used in the Internets Domain Name System. ... .biz is a generic top-level domain (TLD) intended for domains to be used by businesses; the name is a phonetic spelling of the first syllable of business. ... .info is a generic top-level domain intended for informative websites, although its use is not restricted. ...
