How to know your public IP in Linux terminal

Public addresses are allocated by InterNIC and consist of class-based network IDs or CIDR-based address blocks (called CIDR blocks), and are guaranteed to be unique across the global Internet. When a public address is assigned, its route is recorded to a router in the Internet, so that traffic to the public address can be reached smoothly. Traffic to the target public address is reachable via the Internet. For example, when a CIDR block is assigned to an organization in the form of a network ID and a subnet mask, the corresponding [network ID, subnet mask] is also stored as a route in the router on the Internet. The destination is the IP packet of the address in the CIDR block that is directed to the corresponding location. In this article I will cover several ways to view your public IP address in a Linux terminal. This does not make sense for ordinary users, but it can be useful if a Linux server (without a GUI or as a user who can only use basic tools) is logged in. In any case, getting a public IP from a Linux terminal is meaningful in every way, and might be useful someday. Here are the two commands we use primarily, curl and wget. You can use it for a change. Curl Plain Text Format output: Curl icanhazip.com Curl Ifconfig.me Curl curlmyip.com Curl ip.appspot.com Curl IPINFO.IO/IP Curl Ipecho.net/plain Curl www.trackip.net/i Curl JSON format output: Curl Ipinfo.io/json Curl Ifconfig.me/all.json Curl Www.trackip.net/ip?json (a little ugly) Curl XML Format output: Curl Ifconfig.me/all.xml Curl gets all IP details (excavator) Curl Ifconfig.me/all Use Dydns (useful when you use the Dydns service) Curl-s ' http://checkip.dyndns.org ' | Sed ' s/.*current IP address: \ ([0-9\.] *\). */\1/g ' Curl-s http://checkip.dyndns.org/| Grep-o "[[:d Igit:].] \+" Use Wget instead of Curl wget Http://ipecho.net/plain-O-Q; Echo wget Http://observebox.com/ip-O-Q; Echo Using the host and Dig commands If so, you can also use the host and dig commands directly. Host-t a dartsclink.com | Sed ' S/.*has address//' Dig +short myip.opendns.com @resolver1. opendns.com Bash Script Example: #!/bin/bash Public_ip= ' wget Http://ipecho.net/plain-O-Q; Echo ' Echo $PUBLIC _ip Easy to use. I'm actually writing a script to record all the IP changes in my router every day and save it to a file. I found these very useful commands in the search process. Hopefully someday it will help others. If you want to dive into the Linux system novice, you can also download a German Linux software center trial.
