My take from your script is at:

	http://ix.io/1bwE/  [lose the trailing / for the raw file]

NB: I am deliberately using bash instead of dash for a number of reasons....

My script also does the Google DNS lookup.

I've kept the option to use external config file; otherwise it
uses what is known already n the script.

I've used the following for quite some time, but it usually takes too
long (for my liking) to get an answer and it doesn't use https either:

	curl -s ifconfig.me

Kind Regards
