Several ways to query the extranet IP under Linux (GO)

Curl Plain Text Format output:

Curl Icanhazip.comcurl ifconfig.mecurl curlmyip.comcurl ip.appspot.comcurl ipinfo.io/ipcurl ipecho.net /Plaincurl www.trackip.net/I

Curl JSON format output:

Curl ipinfo.io/jsoncurl ifconfig.me/all.jsoncurl www.trackip.net/ip?json (a bit 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)

' http://checkip.dyndns.org ' ' s/.*current IP Address: \ ([0-9\.] *\). */\1/g'-S http://checkip.dyndns.org/| grep-o "[[:d Igit:]. \+"

Use Wget instead of Curl

wget http://ipecho.net/plain-o-Q; Echowget http://observebox.com/ip-o-Q; ech o

Use the host and Dig commands (if available, you can also use the host and Dig commands directly.) ）

' S/.*has address// '  + short myip.opendns.com @resolver1. opendns.com

Bash Script Example:

#!/bin/bashpublic_ip= ' wget http://ipecho.net/plain-o-Q; Echo 'echo $PUBLIC _ip
