Get MAC and IP Address, Network IDs

This c-mex function obtains the MAC and IP addresses and IDs of the computer.

Description

Obtain physical address (MAC) and IP address of the computer. Acts as an MATLAB version 'ipconfig'.

• MATLAB release: MATLAB 6.5 (R13)
• Other requirements: VC6 ++

a more MLbbish solution could look like this (on wintel boxes):
a=strread(evalc('!ipconfig -all'),...
   '%s','delimiter','\n');
a([strmatch('IP A',a),...
   strmatch('Physical',a)])

Here is another solution for getting the IP address that should work on most computers.
MyExternalIP=regexp(urlread('http://checkip.dyndns.org'),'(\d+)(\.\d+){3}','match');

[Marcelo Pisani]

The authour does not provide instructions of how to compile / call the file in Matlab. The solution proposed here by Stephen could not get the MAC number. The solution proposed by Schwarz will fail in non-english versions of IPCONFIG.EXE.

[Michael Kleder]

Good approach if java isn't an option, such as when running matlab with "matlab -nojvm" or if a Java call isn't desired.

If Java is an option, I've had good luck with:
char(java.net.InetAddress.getLocalHost.toString)

I love the speed of this function compared to the dos ipconfig solution. However, I cant seem to figure out how to store the displayed information into a variable?

I have never worked with the mex files, so trying to alter it to spit out output is too hard for me.

Would appreciate help

Here are a way to get MAC address for different systems:
system('getmac'); % windows
system('netstat -I en0'); % mac
system('/sbin/ifconfig eth0'); linux
