This article is to share with you about what network mapping means. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Network mapping refers to network port mapping, that is, a port of the IP address of an external host is mapped to a computer in Intranet to provide corresponding services. When a user accesses this port of IP, the server will automatically map the request to the computer in the corresponding local area network.

Network mapping refers to network port mapping, that is, a port of the IP address of an external host is mapped to a computer in Intranet to provide corresponding services.

When a user accesses this port of IP, the server automatically maps the request to the computer on the appropriate LAN. Port mapping is dynamic and static.

In layman's terms, port mapping maps the IP address of the host's LAN to the IP address of the public network WAN, and when a user accesses the port that provides the mapped port host, the server requests the host network that provides this specific service within the local zone.

Extended data:

Generally speaking, port mapping is to map the LAN IP address of a host to a public network (WAN) IP address. When a user accesses a port that provides a mapped port host, the server transfers the request to the host within the local LAN that provides this specific service. Using the port mapping function, multiple ports of an external network IP address machine can be mapped to different ports on different machines in the internal network.

The port mapping function can also perform some specific proxy functions, such as proxy POP,SMTP,TELNET and other protocols. Theoretically, it can provide a mapping of 65535 (total number of ports)-1024 (number of reserved ports) = 64511 ports.

An example of how to set up port mapping: for example, to map a WEB server with IP address 192.168.111.10, simply fill the IP address 192.168.111.10 of the server and TCP port 80 that provides web services into the router's port mapping table.
