[public-dns-discuss] Re: Getting external IP in app
My question: may i use "o-o.myaddr.l.google.com
" request to google DNS for getting external IP address in my app or this will break terms of using the service?
You shouldn't do this, because it will sometimes return incorrect results due to DNS caching. In any case, the addresses returned from that query are the full address of the DNS resolver at Google (not the user's external IP address) and the subnet (/24 for IPv4 or /56 for IPv6) of the client's external IP address. It does not report the full client IP address
