Since a private IP address never leaves the LAN, the same private IPs appear on different private networks, and they only have to be unique within that single local network.Įach private IP address belongs to one of the following ranges: A private IP address cannot be used to access the Internet and remains only in the local network.

Knowing the private IP address is extremely helpful when troubleshooting a faulty internet connection or configuring advanced network settings. Therefore, by using private IPs, the router properly directs traffic within the network and allows devices on that network to communicate with each other. After receiving or sending data through the public IP address, the router passes that traffic to a specific device using its unique private IP address. The network and router assign a private IP address to a device. Thus, NAT hides the private IP, increasing network security. Users cannot access the Internet directly from a private IP address but must route the connection through NAT, which replaces the private IP address with a public one. Private IP addresses within the same local network must be unique. Private (internal) IP addresses aren't routed on the Internet, they never leave the local network, and no traffic can be exchanged using private IP addresses. Other IP ranges, usually those starting with 10.x.x.x, are within the private IP address range. The number of public IP addresses is far greater than the number of private ones because every network on the Internet must have a unique public IP.Īll public IP addresses belong to one of the following public IP address ranges: Alternatively, use the ip command for an extended range of capabilities compared to ifconfig.
