Six small utilities for checking what your connection is actually doing. Everything runs in your browser — nothing you type here is sent to us or stored.
IP Lookup
City-level location is an estimate from the address registry. It is often the provider’s regional hub, not the actual street.
DNS Lookup
Queries go to Cloudflare’s resolver over HTTPS, so the answer bypasses whatever DNS your router is using.
Ping Test
Browsers cannot send ICMP packets, so this measures an HTTPS round trip instead. Expect it to read a little higher than a command line ping, and to fail on hosts that refuse cross-origin requests.
Port Checker
This only ever checks the connection you are browsing from, so it cannot be used to scan someone else.
IPv6 Test
Checks whether this connection can reach IPv4-only and IPv6-only hosts, then tells you which stack you are running.
Most Indian mobile networks are IPv6 first. Home broadband is often still IPv4 only, which is fine for everyday use.
