Command line app needed to find external ip

[prashanthpai]

I am in search of a command line app that shows ONLY the external dynamic ip address.

But the ipconfig /all shows all info. I only need the external IP.


Also netsh int ip show ipaddress shows extra info besides the external ip


I want to use the command line app in a automated batch file and log (append) the output to a file. So I need a command line app that outputs only the external dynamic ip address without any details or copyright text or developer's name.

There are a lot of GUI apps that show external IP but most of them do not work in command line.

Well, i got many applications to do that, but not a single one in cmd. But tell me, why would you need an application for cmd? when your can use it in GUI?

Are you trying to query against the exip? Like in a bounce, query and send program?

I want to log my external IP to a file after running a series of commands in batch script. I wouldn't mind using a GUI app but I need it to support commandline bcoz I should use it in middle of batch script and append the ouput to a file.

Let me be more clear, for example a very simple command like
ipconfig /all >>output.txt
will append the output of the command to external file "output.txt" like this

I dont think it is possible. but searching hard might help.

Possible and pretty simple.

Download wget from the link below.
http://users.ugent.be/~bpuype/wget/wget.exe

CD to the wget.exe directory and use the following command.
wget -q -O - http://whatismyip.com/automation/n09230945.asp

that'd display your external ip address on the command prompt window. If you want it to output to a file, use the command below.

wget -q -O - http://whatismyip.com/automation/n09230945.asp > IP.txt

I though it is not simple for me

Thanks a lot Raymond. I have been using wget in one of my batch files to download and update the ipfilter.dat file in uTorrent folder but never knew all those long list of switches.

So now I can create a very simple batch file like this which can disconnect and reconnect my net connection (router is in bridge mode) to get a new dynamic IP and then log the new IP.

@echo off

rasdial DataOne /disconnect >NUL
sleep 10 >NUL
rasdial DataOne username password >NUL
wget -q -O - http://whatismyip.com/automation/n09230945.asp >>IP.log
echo. >>IP.log

The sleep utility ^ does not come with XP. I had to get it from Windows Resource Kit.

Thanks again.
