What is the format of ncp?

NCP, or Network Control Protocol, is commonly used in various networking contexts, including Point-to-Point Protocol (PPP) to establish and configure network layer protocols. The format typically includes a header that identifies the protocol type, followed by a series of option fields used to negotiate settings between endpoints. Each option can vary in size, allowing for flexibility in the types of protocols supported. Overall, the format is designed to facilitate the dynamic setup of network connections.
