This page will do a bunch of queries to my backend (and no third-party services!) to identify how you are connected to my site and my content delivery network.

Your IP Address⌗

This queries my backend via an ipv4-only and ipv6-only DNS record, on both the standard (80, 443) and nonstandard (42069) ports, to identify what your public IP address is, and if your (CG)NAT is utilizing different routing for non-standard ports. Some mobile ISPs do dirty tricks with your web traffic, so if these are different, your ISP may be doing something shady.

This doesn’t mean your ISP is definitely doing something shady, and your ISP could still be doing something shady if these match, this is just an indicator.

Content Delivery Network⌗

Since I’m playing with traffic engineering on my CDN, here are some metrics on which CDN endpoint you have reached, and the round-trip time you see, using different traffic engineering methods.

DNS Query Information⌗

The following block is loaded from my DNS server, which provides information on your DNS query.
