What Does Location/Identifier Separation Protocol Mean?
Location/Identifier Separation Protocol (LISP) is a proposed standard for separating current IP address into two separate name spaces to show an IP location and I.D. separately. This standard is in development as a product of the Internet Engineering Task Force, a volunteer group that promotes IT standards and works with other major groups like the W3C and ISO to develop consistent protocols for the Web.

Although certain use cases have been developed for LISP, it is not automatically supported by current IP address standards. As of 2013, the IPv4 standard and updated IPv6 standard still use the address as a single name space. However, with a number of groups and various countries working together on LISP development, and with large companies like Cisco also participating, LISP has the potential to become a common standard. For example, Cisco has already created a LISP mobile IP node client and has further plans to develop LISP-compatible technologies.
While some are enthusiastic about LISP, others have suggested that there may be issues with security and the deployment of LISP protocols. The question of how to consistently upgrade Web systems has also been raised.
