![]() If you are not comfortable with the command line, you can also check the IP address graphically. Some newer Linux distributions don’t include this package anymore and if you try running it, you’ll see the ifconfig command not found error. Long-time users might be tempted to use ifconfig (part of net-tools), but that command is deprecated. You should identify the correct interface and then look beside inet for IPv4 and inet6 for IPv6.įor example, inet 192.168.1.53/24 means the IPv4 address is 192.168.1.53. ![]() They will show you both IPv4 and IPv6 addresses: Display IP Address in Ubuntu Linux You can use this command in the following fashion: ip aĪctually, it’s short for this: ip addr showīoth commands show the same output. The fastest and simplest way to check your IP address is by using the ip command. This is why IPv6 was invented, a format that uses 128-bit addresses (compared to the 32-bit IPv4). However, with the growing number of devices, IPv4 will soon be unable to offer enough addresses. IPv4 is the classic IP format, consisting of a basic 4-part structure, with four bytes separated by dots (e.g., 127.0.0.1). This is used inside this local network without directly exposing the public IP (which the router uses to communicate with the Internet).Īnother distinction can be made between IPv4 and IPv6 protocols. However, in the context of a local network (such as a home where a router is used), each device is assigned a unique private IP address within this sub-network. The public IP address is used to communicate over the Internet, the same way your physical address is used for postal mail. You should also know that there are two types of IP addresses: public and private. The IP address is unique within the network, allowing communication between all connected devices. An IP address serves both the purpose of identification and localisation of a machine. What is an IP Address?Īn Internet Protocol address (commonly referred to as the IP address) is a numerical label assigned to each device connected to a computer network (using the Internet Protocol).
