Looking for information on Protocol UDP 191? This page will attempt to provide you with as much port information as possible on UDP Port 191.
UDP Port 191 may use a defined protocol to communicate depending on the application. A protocol is a set of formalized rules that explains how data is communicated over a network. Think of it as the language spoken between computers to help them communicate more efficiently.
Protocol HTTP for example defines the format for communication between internet browsers and web sites. Another example is the IMAP protocol that defines the communication between IMAP email servers and clients or finally, the SSL protocol which states the format to use for encrypted communications.

Side note: UDP port 191 uses the Datagram Protocol, a communications protocol for the Internet network layer, transport layer, and session layer. This protocol when used over PORT 191 makes possible the transmission of a datagram message from one computer to an application running in another computer. Like TCP (Transmission Control Protocol), UDP is used with IP (the Internet Protocol) but unlike TCP on Port 191, UDP Port 191 is connectionless and does not guarantee reliable communication; it’s up to the application that received the message on Port 191 to process any errors and verify correct delivery.
Because protocol UDP port 191 was flagged as a virus (colored red) does not mean that a virus is using port 191, but that a Trojan or Virus has used this port in the past to communicate.
