Obtain IP address of Logic Machine

[baggins]

Hi,

In some of my scripts it would be useful to know the IP address of the Logic Machine on which they run.
Now I use something I found somewhere:

Code:

require('socket')
local s = socket.udp()
s:setpeername("192.168.1.1",80)
local ip, _ = s:getsockname()
log(ip)

I don't know how it works, but it works (and does not require a connection to the IP address in the script. As a matter of fact that IP address is irrelevant).
Is there a more elegant solution?
Thanks
