Find any IP address & location accurately

IP Address Lookup — Frequently Asked Questions

What’s my IP address?

Your public IP is the address your connection presents on the internet. This page detects it instantly and shows IPv4 or IPv6 along with location and network info.

How accurate is IP geolocation?

City-level accuracy is common but not guaranteed. The data comes from routing tables and commercial datasets, so it can be off by many kilometers, especially on mobile carriers or VPNs.

What do ISP, ASN and CIDR mean?

ISP is the provider that owns or routes the IP. ASN is the autonomous system number the IP belongs to. CIDR is the network block (for example 203.0.113.0/24) allocated by a regional registry.

Can I look up any IP or a domain?

Yes. Paste an IP address or a domain/URL. We normalize the input and resolve the host before returning IP location, reverse DNS and ownership hints.

How do I investigate a website further?

Run a WHOIS lookup for ownership and dates, check DNS records, and verify the certificate with the SSL checker.

Is using this tool free?

Yes. All lookups here are free and rate-limited to keep the service fast for everyone.

IP Lookup: what it shows and how to use it

An IP address lookup is the quickest way to understand where a connection comes from and who routes it. When you open this page, your public IP is detected automatically—no plugin required. Type any other IP address or a full URL into the search box and we’ll normalize it, resolve the host and return fresh geolocation data. Results include country, region and city, the internet service provider (ISP), the autonomous system number (ASN) and useful flags that hint whether the address belongs to a mobile network, a proxy or a hosting provider.

Click IP Intelligence to go a level deeper. You’ll see reverse DNS (PTR), the routed network block (CIDR), registry and allocation date, plus any abuse contacts we can find. These details help developers debug traffic, marketers validate leads and security teams triage signals. The mini-map gives a quick visual—remember it’s approximate. IP geolocation is inferred from routing information, so it’s not the same as GPS accuracy on a phone.

Investigating a website? Pair the IP results with a fast WHOIS lookup to check domain ownership and expiration dates. Use the DNS record viewer to see A, AAAA, MX, TXT and NS records, and confirm encryption with the SSL certificate checker. If you’re auditing a landing page, try the Meta Tag Analyzer and SERP Preview to tune title and description length. Everything runs in your browser with a lightweight backend so it feels instant, even on mobile.

Typical uses: checking whether a login originated from the expected country, confirming if a server is behind a data-center range, filtering test traffic from analytics, or simply sharing a branded snapshot of the results with your team. The Share Snapshot button creates a clean PNG that includes your results and a small footer with our logo, your current URL and timestamp so it’s easy to cite. No tracking pixels, no forced sign-up—just quick answers that save time and keep you moving.
