Re: [Other] DNS errors from The Shining

said by Wily_One:

Why is everyone trying to use ping to troubleshoot DNS? ICMP can be blocked anywhere along the route.

If only there was a TCP-based ping.

TCP based ping will tell you the response time over most any port. It also isn't normally blocked and/or deprioritized like ICMP often is these days. To unsophisticated routers and gateways, it looks like any other TCP-based traffic and tries to pass it along.

tcpinging the dns proxy server will give you just that; and quite honest not sure if it's worth downloading the app.
