You have multiple ways to get your private IP address. Get your Private IP Address with the ifconfig Command There are cases, such as when you are logged on to a Linux server, where you do not have access to a graphical user interface. Or you can also check the other websites we reached with curl to see your IP in the browser. If you have a browser available, you can visit one of the many IP websites out there: You can use wget to retrieve your public IP using the command: $ wget -qO- Using a Browser
Wget is a commonly available utility for Linux that you can use instead of curl to download data and interact with servers.
There are many other servers that can return your public IP address besides these two given above. The output of each command will be your public IP as seen by these servers. You can query servers to return your public IP using the following options: $ curl The curl command is another networking utility that allows you to interact with servers on the internet. Using Curl to Return your Public IP Address
Your IP address will be a series of groups of digits of the format 216.58.216.164 (which is one of the many IP addresses for Google), or a variation of this sort. $ dig +short output you should get back your public IP address from OpenDNS resolvers. Run the following command inside your bash, sh, or other terminal. OpenDNS hosts DNS servers that help discover the IP addresses of networks on the internet. Using dig, you can look up your public IP address by connecting to OpenDNS servers. The dig command is a DNS lookup utility for Linux. Getting your Public IP Address with the dig Command You can discover your public IP address using a variety of commands that connect to the internet to run queries for you.
In turn, the router can route incoming packets to the correct device on the network using network address translation (NAT). Private IP addresses are assigned by your router or another device within the network. When computers connect to the private network, they each get a private IP address to be used within just that network. Internet Service Providers (ISPs) assign public IP addresses, which is akin to your public home address. There is a difference between IP addresses on the public internet and private IP addresses inside a local computer network. Differences Between Public and Private Addresses Under the IP protocol, packets are routed by a path of computers that gets progressively closer to the packet's intended recipient.Įach computer or device on the network is identified by an IP address, which is a numeric identifier unique to that device on the network. IP stands for Internet Protocol, which defines rules that let packets be sent from an origin to a destination computer. The IP protocol, on the other hand, deals with the routing of packets (like those sent by TCP). In particular, TCP checks integrity of transmissions, and provides for re-transmission if packets have not been delivered correctly. TCP stands for Transmission Control Protocol, which is the protocol responsible for the reliable transmission of data over networks. The TCP/IP protocol was invented in 1978 by Bob Kahn, Vint Cerf, and others. This is a networking standard that defines how data is packaged and transferred between computers that are joined together in a computer network. IP addresses arose as part of what's known as the TCP/IP protocol.
What is an IP Address? Understanding the TCP/IP Protocol
BSD systems like FreeBSD and NetBSD, as well as Mac OS, might also be able to read their IP addresses using these instructions. These instructions will work for most of the various Linux distributions like Ubuntu, Debian and Linux Mint, among others.
In this guide, we will show you how to find your own IP address.
IP addresses are an essential part of modern networked communications.
