Which RFC defines the Internet Protocol (IPv4)?

Explanation:
The document that defines the Internet Protocol version 4 is RFC 791. This RFC laid out the fundamental structure and behavior of IPv4, including the header format, addressing, how datagrams are formed, and how they are routed and may be fragmented across networks. It establishes the core mechanics that enable IP packets to be transmitted between hosts on different networks. The other RFCs mentioned describe different protocols: RFC 768 covers the User Datagram Protocol (UDP), RFC 792 covers the Internet Control Message Protocol (ICMP), and RFC 793 covers the Transmission Control Protocol (TCP). These are separate protocols that operate at the transport or diagnostic layers, not the IP layer itself.
