IP access controllers may have an internal web server that is configurable using a browser or using software installed on a host PC. The main features that distinguish IP controllers from older generations of serial controllers are: # IP controllers connect directly to LAN or WAN # IP controllers have all the inputs and outputs necessary for controlling readers, monitoring door inputs, and controlling locks # IP controllers have an on-board network interface and do not require the use of a terminal server Advantages and disadvantages of IP controllers Advantages: * An existing network infrastructure is fully utilized; there is no need to install new communication lines. * There are no limitations regarding the number of IP co ...

V, or v, is the twenty-second and fifth-to-last letter in the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide.

The pointed form "v" was written at the beginning of a word, while a rounded form "u" was used in the middle or end, regardless of sound. So whereas "valour" and "excuse" appeared as in modern printing, "have" and "upon" were printed as "haue" and "vpon". The first distinction between the letters "u" and "v" is recorded in a Gothic script from 1386, where "v" preceded "u".

Internet Protocol
The Internet Protocol (IP) is the network layer communications protocol in the Internet protocol suite for relaying datagrams across network boundaries. Its routing function enables internetworking, and essentially establishes the Internet. IP has the task of delivering packets from the source host to the destination host solely based on the IP addresses in the packet headers. For this purpose, IP defines packet structures that encapsulate the data to be delivered. It also defines addressing methods that are used to label the datagram with source and destination information. IP was the connectionless datagram service in the original Transmission Control Program introduced by Vint Cerf and Bob Kahn in 1974, which was complemented by a connection-oriented service that became the basis for the Transmission Control Protocol (TCP). The Internet protocol suite is therefore often referred to as ''TCP/IP''. The first major version of IP, Internet Protocol Version 4 (IPv4), is the do ...
