One fast page for IP checks, DNS records, port probes, password generation, and HTTP latency.
Everything is laid out as a single toolbox: browser-friendly inputs, clear loading states, and server routes where the browser cannot do the job honestly.
How it works
IP and DNS checks go through public resolvers or a server route, so cross-origin restrictions do not block the result.
Port and latency tools run on the server, where TCP sockets and external fetches are actually possible.
Password generation uses crypto-grade randomness and can be copied in one click.
Network snapshot
IP checker
Checks your public IP through a server route, so browser CORS limits do not get in the way.
Public address and source appear here after the request finishes.
Public IP, source label, and network status will appear after the first refresh.
Resolver scan
DNS lookup
Look up A, AAAA, CNAME, MX, NS, or TXT records through a public resolver and show clear no-data states.
Query a domain to inspect public records. Select all records for a quick broad scan.
Example: example.com
TCP probe
Port checker
Check whether a TCP port is open, closed, or timing out through a server-side socket probe.
Use a host and port pair to test if a TCP service is reachable. Example: example.com and 443.
Crypto output
Random password generator
Build strong passwords with crypto-grade randomness, category toggles, and one-click clipboard copying.
Presets
Uses the browser's crypto API, then falls back to a clipboard helper if needed.
Generated password
Password appears here after generation.
Generate a password to begin.
HTTP timing
Latency test
Measure HTTP round-trip latency to a public URL. This is browser-safe network timing, not ICMP ping.
Test latency against a URL that supports HTTP requests. The route reports the response time and HTTP status code.
