Endpoint Identifier


An Endpoint Identifier, in technology, commonly refers to a specific address or identification for a device connected to a network. This could be an IP address, a URL, or a device-specific ID which allows for the unique identification and communication with that device within the network. The identification is crucial for various processes like data transfer, network security, or system management.


The phonetic pronunciation of “Endpoint Identifier” is /ˈɛndˌpɔɪnt aɪˈdɛntɪfaɪər/

  1. An Endpoint Identifier or EID is a specific type of identifier used across networks. It helps in recognizing the end of communication devices within a specific network.
  2. EIDs aid in managing the communication process within a network. It is instrumental in determining the source and destination of data, making it particularly crucial for data transfer over networks.
  3. The EID is a component of the Locator/ID Separation Protocol (LISP), which separates the network device’s identity and its location to improve network routing scalability.

Endpoint Identifier is a crucial term in technology, particularly in the field of networking and communication. It refers to a unique sequence of characters, numbers, or symbols used to identify a specific network endpoint, which could be a device, a server, or a particular system in a network. This identifier allows the efficient routing of data packets between the source and destination points in a network, thereby enabling smooth and organized communication. In distributed systems, IoT devices, or networks involving numerous devices, endpoint identifiers play a vital role in managing complex data traffic to ensure that the right data goes to the right endpoint. So, the importance of Endpoint Identifier largely lies in its function of supporting effective and secure data transmission within a network.


Endpoint Identifier serves a crucial purpose in the world of computing, particularly in network communications and internet protocol (IP) systems. Fundamentally, it is used to uniquely identify an endpoint in a network, expediting direct communication and data exchange between devices. In traditional IP networking, the network address of a device, usually referred to as the IP address, functions as its identifier. However, in advanced networking architectures like Locator/Identifier Separation Protocol (LISP), the two components are separated, and the endpoint identifier comes into play to explicitly identify a device. This aids in efficient routing and seamless communication, without depending on the physical location of a device.The use of an endpoint identifier enhances the flexibility and precision of the communication process. This mechanism is especially invaluable in mobile or cloud networks where devices frequently change their network point of attachment. By using an endpoint identifier, a device remains reachable even if it changes its network location, fostering a stable communication system. Additionally, separating the identifier from the locator simplifies network management and enhances scalability. Therefore, an endpoint identifier plays a pivotal role in ensuring seamless, effective, and efficient communication within a network.


1. Mobile Phone Number: In a telecommunication network, a mobile phone number serves as a unique identifier representing the ‘end point’ or device in the network. No other device will have the exact same number; this endpoint identifier is unique and distinctive.2. IP Address: An Internet Protocol (IP) address in a network is a unique identifier associated with all devices (computer, printer, router, etc.) connected to a network. It serves as the endpoint for data transmissions.3. Device MAC Address: A Media Access Control (MAC) address is a unique identifier assigned to a network interface controller (NIC) for communications at the data link layer of a network segment. It serves as an endpoint identifier for data transmissions via Ethernet or Wi-Fi network.

Frequently Asked Questions(FAQ)

Q: What is an Endpoint Identifier?A: An Endpoint Identifier (EID) is a unique identifier used in computer networks to identify a specific network node, such as a device, server, or interface, in a communication transaction or across a network.Q: Is an Endpoint Identifier the same as an IP address?A: No, an EID is not the same as an IP address. An IP address is used for routing data, while an EID is used for identifying the endpoint that sends or receives this data.Q: How does an Endpoint Identifier work?A: In a network setting, when a node wants to send data to another node, it references the endpoint with its EID. The network then finds the best path to that endpoint and sends the data to the EID’s associated routing locators.Q: Where is Endpoint Identifier used?A: Endpoint Identifiers are used significantly in the Locator/ID Separation Protocol (LISP), a network protocol developed by Cisco. They are also commonly used in other IP-based networks.Q: Can an Endpoint Identifier change?A: No, EIDs are meant to be static, remaining the same regardless of the point the node is connected to in the network. Q: Why is an Endpoint Identifier important?A: Endpoint Identifiers are important as they enable data to be appropriately distributed and managed over a network by reliable identification of nodes. They play a crucial role in the operational efficiency and robustness of network systems.
