curl ip.appspot.com

curl ipecho.net/plain
curl www.trackip.net/i

curl ifconfig.me/all.json
curl www.trackip.net/ip?json (bit ugly)

curl all IP details – The motherload

curl ifconfig.me/all

Using DYNDNS (Useful when you’re using DYNDNS service)

curl -s 'http://checkip.dyndns.org' | sed 's/.*Current IP Address: \([0-9\.]*\).*/\1/g'
curl -s http://checkip.dyndns.org/ | grep -o "[[:digit:].]\+"

Using wget instead of curl

wget http://ipecho.net/plain -O - -q ; echo
wget http://observebox.com/ip -O - -q ; echo

Using host and dig command (cause we can)

You can also use host and dig command assuming they are available or installed

host -t a dartsclink.com | sed 's/.*has address //'
dig +short myip.opendns.com @resolver1.opendns.com

Sample bash script:

#!/bin/bash

PUBLIC_IP=`wget http://ipecho.net/plain -O - -q ; echo`
echo $PUBLIC_IP
