几种在Linux下查询外网IP的办法(转)

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 ipinfo.io/json
curl ifconfig.me/all.json
curl www.trackip.net/ip?json (有点丑陋)

curl ifconfig.me/all.xml

curl ifconfig.me/all

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

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

host -t a dartsclink.com | sed ‘s/.*has address //‘
dig +short myip.opendns.com @resolver1.opendns.com

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