Internet Times is a free network-diagnostics suite for engineers, sysadmins, and curious developers. DNS, IP, SSL, MX, WHOIS, HTTP headers, reverse DNS, and bandwidth — diagnosed in your browser, never gated by a signup.
What we run
Eleven tools today, designed to mirror what an engineer would type into a terminal. Each tool runs the same query a sysadmin would run from a shell — DoH for DNS, RFC 3912 WHOIS on port 43, a real TLS handshake for SSL, parallel curl-style HEAD requests for HTTP headers, and ICMP-style timing for the speed test. No scraping, no stale caches, no marketing fluff between you and the wire.
- DNS Checker — multi-resolver propagation across Google, Cloudflare, Quad9, and OpenDNS.
- DNS Lookup — every common record type for a domain on one page.
- Reverse DNS — PTR records with FCrDNS verification.
- WHOIS Lookup — registrar, dates, and status codes.
- MX Record Lookup — mail servers, SPF posture, and DMARC policy.
- What is My IP — your IPv4 and IPv6 with ISP and geolocation.
- IP Lookup — geolocation, ASN, and abuse contact for any IP.
- IP Blacklist Check — 11 active public RBLs in parallel.
- SSL Certificate Checker — subject, issuer, validity, and SAN list.
- HTTP Header Inspector — response headers plus a security-headers audit.
- Speed Test — download, upload, ping, and jitter from your browser.
How we are different
- No signup, no account, no rate limits on the public UI. Free tools run for anyone. The optional REST API uses keys, but the public web is wide open.
- No third-party trackers by default. No Google Analytics, no Facebook pixels, no ad-network beacons. See the privacy policy for the exact list of cookies we set.
- Honest results. If a query times out, we say it timed out. If a record is missing, we say it is missing. We never fabricate plausible-looking numbers to fill the screen.
- JSON on every endpoint. Every tool result is also available as JSON via the REST API — 100 calls/day free, paid plans for higher volume.
- Open source mentality. Plain PHP, plain MySQL, no framework lock-in. Edit a file, refresh the browser.
Who builds this
Internet Times is built and maintained by a small team of engineers who got tired of slow, ad-heavy diagnostic sites. The tools you use here are the same tools we use at our day jobs, hardened and put behind a clean UI.
