This one's a bit flaky...better ways to do it...
Here's a crude way to get your public ip address from batch without service! [no whatismyip,etc]
Using tracert, traces the route to a non-existant website [1.1.1.1, or use *any* address] and watches the server hops as it goes out..
It ignores 192. and 10. and 172.x.x.x adresses so should skip the internal adapter and router..[ymmv tho]
It may need tweaking if you use weird local ip, or multiple routers..
but once you tweak it for your setup if needed, it should work fine from then on...[unless you add another router hop in the mix]
I'm curious to hear what setups it DOESN't work on... let me know..
here 'tis:
or a one liner:
Replace @echo with 'set publicip=' and you now have a variable you can process further..
Handy for navigating back to your EWA, you could email ip to yourself when it changes..
Enjoy
