4 Ways to Find Server Public IP Address in Linux Terminal

In computer networking, an IP (Internet Protocol) address is a numerical identifier assigned permanently or temporarily to every device connected to a network that uses the Internet Protocol for communication. Its two major functions are to identify a network or host on a network and also serve for location addressing.

There are currently two versions of IP addresses: IPv4 and IPv6, which can either be private (viewable within an internal network) or public (can be seen by other machines on the Internet).

Additionally, a host can be assigned a static or dynamic IP address depending on the network configurations. In this article, we will show you 4 ways to find your Linux machine or server public IP address from the terminal in Linux.

1. Using dig Utility

dig (domain information groper) is a simple command line utility for probing DNS name servers. To find your public IP addresses, use the opendns.com resolver as in the command below:

$ dig +short myip.opendns.com @resolver1.opendns.com

2. Using host Utility

host command is an easy-to-use command line utility for carrying out DNS lookups. The command below will help to display your systems public IP address.

$ host myip.opendns.com resolver1.opendns.com | grep "myip.opendns.com has" | awk '{print $4}'

Important: The next two methods employ third party websites to display your IP address on the command line as described below.

3. Using wget Command Line Downloader

wget is a powerful command line downloader that supports various protocols like HTTP, HTTPS, FTP and many more. You can use it with third party websites to view your public IP address as follows:

$ wget -qO- http://ipecho.net/plain | xargs echo
$ wget -qO - icanhazip.com

4. Using cURL Command Line Downloader

curl is a popular command line tool for uploading or downloading files from a server using any of the supported protocols (HTTP, HTTPS, FILE, FTP, FTPS and others). The following commands displays your public IP address.

$ curl ifconfig.co
$ curl ifconfig.me
$ curl icanhazip.com

    You can also use the following command to find out IP address.

    # curl ipconfig.in/ip
  3. Mike Francis says:

    How about a simple ping or nslookup?

    • Aaron Kili says:


      Here, we explained how you can get your own public IP address, say on a laptop, from the terminal. Sometimes a ping doesn’t show your public IP address, and nslookup is not appropriate for this, unless you are finding the IP address associated to a domain name.

  4. Zakir Shaikh says:

    curl -L0 http://checkip.org 2>/dev/null | grep ‘IP Address’ | awk -F ‘>’ ‘{ print $3 }’ | awk -F ‘<' '{ print $1 }'

    curl http://wooledge.org/myip.cgi

    These 2 works good for me …
    And thanks for excellent articles…
