Get IP info with Linux command

NameStuff · January 2014

This gets the local host's public IP info:

$ curl -L q.dynaip.net

{"timezone":"America\/New_York","isp":"Lightstream Transmission and Telecom Inc","region_code":"GA","country":"United States","dma_code":"0","area_code":"0","region":"Georgia","ip":"199.233..","asn":"AS7363","continent_code":"NA","city":"Atlanta","postal_code":"30303","longitude":-84.3915,"latitude":33.7516,"country_code":"US","country_code3":"USA"}

This gets any IP info you want, for example, 8.8.4.4,

$ curl -L q.dynaip.net/8.8.4.4

{"country":"United States","dma_code":"0","area_code":"0","ip":"8.8.4.4","asn":"AS15169","continent_code":"NA","isp":"Google Inc.","longitude":-97,"latitude":38,"country_code":"US","country_code3":"USA"}

Maybe you somebody else has known that, but I found it's useful for me.

I prefer curl getipaddr.net

I use dig +short myip.opendns.com @resolver1.opendns.com in my auto IP update script.

I just wrote a related blog article at http://bit.ly/1cPd7Lw. You can also click on my signature. Anyone interested in automatically updating their VPS' Public IPs upon deployment (for example on Amazon EC2 or DigitalOcean) are welcome to take a look.

Edit: I may have misunderstood the OP's question... My method was for getting one's public IP.

I prefer

curl http://ipecho.net/plain

I guess people here are talking about different things. Afaik the OP doesn't simply want to see his public facing IP, but instead get some more detailed information about the IP itself (as posted).

If you just want to get your public IP without relying on external services a ifconfig |grep -B1 "inet addr" |awk '{ if ( $1 == "inet" ) { print $2 } else if ( $2 == "Link" ) { printf "%s:" ,$1 } }' |awk -F: '{ print $1 ": " $3 }'should do the trick. (This is interface independent.)

If you are inside NAT, you see your private ip(s) when you use this command.

tux@g6:~$ ifconfig |grep -B1 "inet addr" |awk '{ if ( $1 == "inet" ) { print $2 } else if ( $2 == "Link" ) { printf "%s:" ,$1 } }' |awk -F: '{ print $1 ": " $3 }'
