Internal IP AddressesĪ private IP address is assigned to each device in the local network by the router they are connected to. The addresses you are connecting to are called remote IPs.Ī public IP is also referred to as an outward-facing IP. External IP AddressĪn external IP address is another name for a public IP address - it works outside the local network, allowing users to connect to the Internet and communicate with other public IP addresses worldwide. This section answers some frequently asked questions about public and private IP addresses. Public IPs require additional security measures, they are prone to attacks.įAQs About Public and Private IP Addresses Used to communicate within a private network.Ī unique address not used by other devices on the Internet.Īn address from a smaller range used by other devices in other local networks.Īssigned by the router to a specific device on the local network.Īny IP not in the private IP address ranges. The following table summarizes the key differences between a public and private IP address: Category Therefore, public IPs are used to interact and communicate online, while private IPs operate within a local network. The crucial difference between a public and private IP address is that the public IP can be seen by other devices on the Internet, while the private IP cannot. Difference Between Public and Private IP Address Since private IP addresses are reserved for private networks and need to be unique to that network only, the ranges are much smaller than for public IP addresses. Ranging from 192.168.0.0 to 192.168.255.255, it is for smaller networks and has 24 bits for the network and 8 for hosts. Ranging from 172.16.0.0 to 172.31.255.255, it is used for medium networks and has 16 bits for the network and 16 for hosts. Ranging from 10.0.0.0 to 10.255.255.255, it is for large networks and has 8 bits for the network and 24 for hosts. 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. Private IP RangesĮvery private IP address belongs to a specific private IP address range reserved for that purpose by the Internet Assigned Numbers Authority (IANA). Your private IP address is under the Status section. Press the Windows key and type PowerShell. Follow the steps below to find your private IP address:ġ. 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. For Linux users, follow our tutorial to obtain your IP address using the hostname or ifconfig command, or via the GUI.
