Why No Built in GetMyIP call in LiveCode?

Hi All...

I've been looking at all the solutions in the archive for getting the  
IP address of the machine running a stack. Some shell scripts, some  
php calls, etc. etc.

I have a situation where we are behind a firewall using NAT. So all  
our computers are running a 10.x.x.x.x address. I'm trying to  
implement some socket communication between stacks and IP address  
information is essential for this to work. I would like the  
communication process set up to be as transparent as possible,  
allowing users to connect by name and maybe holding IP address is a  
custom property for example.

The Dictionary provides some examples for hostAdress function and I  
tried (wishful thinking, script trickery) something like this:

on mouseUp
    open socket to "" with message "socketOpen"
    put the result
end mouseUp

on socketOpen theSock
    put the hostAddress of ""
end socketOpen

...but it just gave me and not the 10.x.x.x. address...

Shell script works nice, but it gives quite a few IP in its result.  
Plus the actual machine IP is located on different lines in the  
result, such as in a desktop machine, as opposed to a laptop on  

It just seems like it would be nice to have a built in function for  
reporting local machine's IP...

Such as, "put localIP of current stack into tIP"  or "get LocalIP of  
current stack."

Is this available in the dictionary and I'm just missing it?

Thank you!
