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
