Overview IP

The Internet Protocol (IP) is based on data packets. It is used in data exchange between computer networks. The protocols that are supported by the device include: IP, Internet Control Message Protocol (ICMP), Transfer Control Protocol (TCP), User Datagram Protocol (UDP), and Socket.

Among them, IP packets are the base of the TCP/IP protocol stack. The IP layer is responsible for addressing, fragmentation, reassembly, and protocol information partitioning. As the network layer protocol, the IP protocol performs route addressing and control packet transmission.

The UDP protocol and the UDP protocol is set up based on the IP protocol. They provide connection-based reliable data transmission services and non-connection-based unreliable data transmission services respectively.

ICMP is mainly used to provide network detection services. It also provides an error report if the network layer or transmission layer protocol becomes abnormal, and it informs the related device of the abnormality to facilitate network control management.
