Public IP address, WAN IP address
Public IP and WAN IP are external addresses, each user has a public IP, and this IP is not duplicated, it is unique, and users can access and apply the Internet through public IP and WAN IP.
Private IP addresses and private IP addresses
Intranet IP and private IP are the same nature, generally intranet IP is also called LAN IP, he is an internal access address, this address is not exposed to the public network, it is provided by enterprise network equipment, such as routers and switches, this IP address is private, can only be applied in the intranet, can not be used externally.
Static IP address, dynamic IP address
As the name suggests, a static IP is a fixed IP address, and a dynamic IP is an address that changes irregularly, and the two of them are relative. In the internal application of the enterprise, the application is generally connected to the application through the internal IP, and if the external network is generally connected to the application through the public IP, the scope of use of the two is different, but in the actual application environment, it is found that many public IP are also converted into intranet IP by the network operator, and if this happens, it is impossible to realize remote access to the application.
