Several ways to query the IP of the outside network under Linux

Original address: http://my.oschina.net/epstar/blog/513186

Curl Plain Text Format output:

ifconfig . Mecurl curlmyip.comcurl ip.appspot.comcurl ipinfo.io/ipcurl ipecho.net/Plaincurl Www.trackip.net/I

Curl JSON format output:

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

Curl XML Format output:

ifconfig. Me/all.xml

Curl gets all IP details (excavator)

1 ifconfig. Me/all

Use Dydns (useful when you use the Dydns service)

' http://checkip.dyndns.org ' sed ' 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; Echo

Using the host and Dig commands

If so, you can also use the host and dig commands directly.

sed ' 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

Nmap
