It checks public IPv4/IPv6 addresses across standard and non-standard ports to detect ISP traffic manipulation, tests browser support for HTTP versions (h1, h2, h3) via DNS record combinations, probes cryptographic algorithm support including RSA, ECDSA, and post-quantum ML-DSA certificates, and shows CDN traffic engineering metrics (DNS vs BGP routing) with latency data. ML-DSA support currently requires Chrome Canary or a recent OpenSSL/curl build. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Which browsers currently support ML-DSA certificates for TLS? Only Chrome Canary supports ML-DSA certificates in a browser. However, recent versions of OpenSSL also support ML-DSA, which means curl can use them as well. ML-DSA is not yet available through public certificate authorities, so testing requires manually trusting a self-signed certificate. _Developers tracking post-quantum TLS adoption across browsers follow developments like this on daily.dev._ ### How can I tell if my ISP or CGNAT is doing something shady with my web traffic? Comparing your public IP address as seen on standard ports (443) versus a non-standard port (e.g., 42069) can reveal ISP traffic manipulation. If the IPs differ, your ISP or CGNAT may be routing non-standard port traffic differently. Matching IPs do not guarantee clean routing, but differing IPs are a clear indicator of interference. _Network engineers watching for ISP routing anomalies keep up with diagnostic techniques like this on daily.dev._ ## Similar posts on daily.dev - [We have ipinfo at home or how to geolocate IPs in your CLI using latency](https://daily.dev/posts/we-have-ipinfo-at-home-or-how-to-geolocate-ips-in-your-cli-using-latency-lmjbqeqot) · Hacker News · 1 upvotes · 0 comments - [Introducing Networking Toolbox: Self-Hosted Network Tools in One Place](https://daily.dev/posts/introducing-networking-toolbox-self-hosted-network-tools-in-one-place-v5pcojgyj) · Noted · 24 upvotes · 0 comments - [Understanding IP Addresses: What They Reveal and How VPNs Change Your Online Connections](https://daily.dev/posts/understanding-ip-addresses-what-they-reveal-and-how-vpns-change-your-online-connections-akqxy6mce) · SitePoint · 0 upvotes · 0 comments - [Here's how your ISP and the entire internet know that you're using a VPN](https://daily.dev/posts/here-s-how-your-isp-and-the-entire-internet-know-that-you-re-using-a-vpn-6ajuofpto) · XDA Developers · 0 upvotes · 0 comments --- Tags: [#networking](https://daily.dev/tags/networking), [#dns](https://daily.dev/tags/dns) [View this post on daily.dev](https://daily.dev/posts/what-is-my-ip--e0qwm1zwi) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"What Is My IP?","url":"https://daily.dev/posts/what-is-my-ip--e0qwm1zwi","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/what-is-my-ip--e0qwm1zwi"},"datePublished":"2026-08-11T08:56:45.058Z","dateModified":"2026-08-11T09:28:51.155Z","description":"A diagnostic web tool that queries a self-hosted backend (no third-party services) to reveal how a visitor is connected to the site.
