What Is My IP Address?

“What is my IP?” remains one of the most searched webmaster queries because so many systems key off the address you appear to use: firewall allowlists, DNS provider ACLs, API rate limits, game server bans, and abuse reports. DNS Checkers shows the address of the TCP connection that reached this application. If you use a VPN, corporate proxy, or carrier-grade NAT, the address belongs to that intermediary — not necessarily the Wi-Fi router in your living room.

IPv4 versus IPv6

Networks increasingly offer IPv6. When your path to DNS Checkers is IPv6 end-to-end, we display that address. When the path is IPv4, you will see IPv4. Dual-stack clients still pick one connection for a given request; this page reports that chosen path rather than inventing both families if only one was used. For reverse mapping of the displayed address, open Reverse DNS.

User-agent and language headers

Alongside the IP we surface your User-Agent and Accept-Language headers. These help confirm whether you are on a desktop browser, mobile WebView, or scripted client. They are not perfect fingerprints and should not be treated as identity proofs.

Privacy and AdSense-safe operations

IP addresses can be personal data under GDPR depending on context. We use them for security, rate limiting, and optional contact-form abuse prevention. Advertising cookies load only after consent; Reject on the banner works. Read the Privacy Policy and Cookie Policy for details.

Phase 2 expands ISP/ASN style lookups using free data sources only. Until then, this page stays focused on truthful connection facts without selling paid geolocation APIs.

Allowlists and break-glass access

Developers often need to allowlist their current IP on staging firewalls, database admin panels, or DNS provider APIs. Copy the address from this page carefully, and remember it can change when you leave café Wi-Fi or reconnect a VPN. Prefer short-lived allowlists and SSO where possible instead of permanent /32 exceptions that accumulate into a security mess.

If your company uses egress proxies, every employee may appear as the same IP — which is great for allowlists and terrible for per-user abuse tracing. Document that reality in your runbooks. DNS Checkers shows what the internet sees right now; it does not replace identity-aware access controls. Combine with reverse DNS and upcoming ISP lookup tools when you need to explain an address to a vendor support agent.

For educators: ask students to load this page on cellular data versus campus Wi-Fi and explain why the addresses differ. That single exercise demystifies NAT better than a slide deck.
