Apple

So now I'm stuck, as the exact code I just posted (see above), doesn't
work. The internet connection test code (when taken out) doesn't fix
the issue, so my thinking is that there must be a newer way for the
Wan IP address retrieval to occur in OS X 10.11, but I've not been
able to figure it out as of yet.
Any help is much appreciated.
Thanks.

This is the code I've been using. I don't have 10.11 to test, but this might work for you:

tell application "Finder"

set internalIP to ""

set my_interface to ""

try

set my_interface to do shell script "netstat -rn -f inet | egrep \"^default\" | awk '{print $6}' "

display dialog my_interface

if [my_interface is equal to ""] then

error "no default interface found"

else

set internalIP to do shell script "ipconfig getifaddr " & my_interface

end if

on error

set internalIP to "internal IP not found, or no default interface found"

end try

display dialog internalIP

end tell
