Graphics Protocol
Port 41 is officially registered for the Graphics protocol, intended for experimental or legacy graphics or imaging data transmission. However, it is rarely used in modern networks, and its initial scope of enabling graphics exchange across networked devices is largely obsolete. Today, it often appears in port lists for legacy reasons rather than active service deployment..
Port 41 is allocated by IANA for the Graphics protocol, initially designed to support experimental graphics or image data communication. Such protocols aimed to facilitate device-independent graphic information exchange in a structured and potentially real-time manner. Though exact protocol specifications are limited, the intention was to standardize graphics data transmission using this port.
Given the rapid evolution of graphical standards, port 41 never saw widespread adoption. Modern graphics protocols shifted toward application-layer standards such as HTTP(S), RTP, and specialized streaming protocols that offer better compression, security, and compatibility. As a result, the original usage for port 41 is largely historical.
Today, traffic on port 41 is uncommon; it is largely observed through residual scans or legacy applications. While technically present in the official port listings, active deployment of the underlying graphics protocol is practically nonexistent in commercial and enterprise environments.
