DTNS Connect

About

DTNS Connect shows what is really happening on your network — no account, no sign-up, no charts for the sake of charts. DNS CHECK • See which DNS servers your router or carrier handed out, and who runs them • Compare their answers with Cloudflare, Google, Quad9 and AdGuard over DNS-over-HTTPS • Detect tampering: NXDOMAIN hijacking, ISP placeholder pages, mismatches with public resolvers • Query any domain by hand — A, AAAA, CNAME, MX, TXT, NS, HTTPS — with the system answer next to every resolver SPEED AND LATENCY • Download, upload, response time and jitter over the Cloudflare network • TCP latency to reference hosts: best, average, jitter and packet loss SERVICE REACHABILITY • Fourteen popular services checked in three steps: DNS → TCP → TLS • Not just "it does not work", but where it breaks: name resolution, IP reachability or the TLS handshake YOUR OWN SERVERS • vless://, vmess://, trojan://, ss:// links and subscriptions are parsed into readable parameters • Protocol, security, transport, SNI, flow and Reality keys on a single screen • Latency measurement for every server so you can pick one that is alive and fast REPORT • Every result is collected into a plain-text summary you can send to your ISP support PRIVACY • No account, no analytics, no backend of our own • Server configurations never leave the device • Only the checks themselves go out — to the resolvers you picked and to Cloudflare DTNS Connect is not a VPN and does not route your traffic. It measures and reports.
