What is Locator/ID Separation Protocol (LISP)?

Locator/ID Separation Protocol (LISP) is a routing architecture that fundamentally changes the way that IP addresses are assigned. Traditionally, an IP address includes both a device's identity and its location in a single number. LISP separates the device identity and its location into two separate numbers: an identifier and a locator. By doing this, LISP simplifies multihomed routing, allows for scalable any-to-any WAN connectivity, and it supports virtual machine mobility within a data center.

LISP supports both IPv4 and IPv6 addresses, and the identifiers and locators it creates can be either IP addresses or arbitrary elements, such as a MAC address or a GPS coordinate.

You do not need to implement LISP in your IP network all at once. You can gradually introduce it.

Many vendors have implemented LISP, such as Cisco. There is also an open standard called OpenLISP. This is not to be confused with the Lisp programming language.
