Detecting IP address…

What Is an IP Address Detector?

An IP address detector is a free online tool that instantly reveals your public IP address along with related network and location information — your approximate city, country, internet service provider (ISP), timezone, and autonomous system number (ASN). The moment you load this page, your browser's public-facing IP is automatically detected and displayed without you clicking anything or signing up for an account.

Every device connected to the internet is assigned a public IP address by its internet service provider. This address acts like a return address for data traveling across the web, allowing websites, servers, and other devices to know where to send information back to you. This tool reads that address directly from your connection and cross-references it against IP geolocation databases to surface useful details about your network.

If you are troubleshooting a domain or email issue alongside your IP lookup, our DNS lookup tool lets you check a domain's A, MX, TXT, and NS records in real time — a natural companion when diagnosing connectivity problems.

Why Would You Need to Check Your IP Address?

What Information Does This Tool Show?

The table below explains each data point this IP detector returns and what it tells you about your connection:

FieldWhat It ShowsWhy It Matters
Public IP AddressYour IPv4 or IPv6 address as seen by external serversRequired for remote access, port forwarding, VPN verification
City & RegionApproximate geographic location from ISP-assigned IP rangesHelps diagnose geo-restriction issues and VPN location checks
CountryCountry your IP block is registered to, with country codeExplains why region-locked content is or isn't accessible
ISP / OrganizationThe company that owns the IP block (your internet provider)Useful for reporting abuse, checking blacklists, or contacting support
TimezoneLocal timezone associated with your detected locationHelpful when scheduling across time zones or debugging timestamps
ASNAutonomous System Number identifying your network operatorUsed in network engineering, peering analysis, and abuse reporting
CoordinatesApproximate latitude and longitude of the IP's registered locationShows the general area, not your exact address — typically city-level

How to Use the IP Address Detector

IPv4 vs. IPv6 — What Is the Difference?

The internet uses two versions of the IP addressing system. This tool automatically detects which one your connection is using.

FeatureIPv4IPv6
FormatFour decimal numbers (e.g. 192.168.1.1)Eight hexadecimal groups (e.g. 2001:0db8::7334)
Address Length32-bit128-bit
Total Addresses~4.3 billion~340 undecillion (virtually unlimited)
AdoptionUniversal — still the majority of trafficGrowing — most modern ISPs support both
NAT Required?Yes — ISPs share addresses via NATNo — every device can have a unique address
Header ComplexityMore complex, variable-lengthSimplified, fixed-length — faster routing

IPv4 is the older, more widely used system. Because its 4.3 billion addresses have essentially run out, ISPs increasingly assign IPv6 addresses to new connections. Most devices and networks support both simultaneously, and this detector automatically identifies which version your connection is using.

Public vs. Private IP Addresses

Your home or office network actually uses two types of IP addresses, and understanding the difference is important for troubleshooting:

When you set up port forwarding, configure a VPN, or share your IP with IT support, they need your public IP — not your private one. This tool always shows the public address.

How IP Geolocation Works — And Its Limitations

IP geolocation maps an IP address to a geographic location by cross-referencing it against databases maintained by regional internet registries (RIRs) and commercial geolocation providers. These databases track which IP ranges are assigned to which ISPs, and where those ISPs operate geographically.

The result is an approximation, not a GPS fix. Here is what you can generally expect in terms of accuracy:

If the city shown does not match your actual location, it is usually because your ISP routes your traffic through a regional hub in a different city. This is especially common with mobile data connections, satellite internet, and carrier-grade NAT setups.

Is It Safe to Share Your IP Address?

Sharing your public IP address carries minimal risk in most situations. It does not reveal your exact physical address, name, or personal identity — only an approximate location tied to your ISP's regional infrastructure, which is often a city or region away from where you actually are.

That said, it is good practice to avoid sharing your IP with untrusted parties. A determined attacker with your IP could potentially attempt port scanning, DDoS attacks, or social engineering against your ISP. Using a VPN masks your real IP and adds a layer of protection in situations where privacy matters.

This tool runs the lookup directly from your browser to a geolocation API — we do not log, store, or track the IP addresses or results you look up.

Common IP Address Troubleshooting Scenarios

VPN Not Working as Expected

Connect to your VPN, then reload this page. If the IP address shown is still your real one (same city, same ISP), the VPN connection is not active or is leaking your real IP. Try reconnecting, switching VPN protocols, or contacting your VPN provider's support.

Remote Access Not Connecting

If you are trying to access your home computer remotely and the connection fails, confirm that the public IP you shared has not changed. Many ISPs assign dynamic IPs that rotate periodically. Check this tool to see your current IP and update your remote access configuration if it has changed.

Website or Service Thinks You Are in the Wrong Country

Some streaming services, banking apps, and government websites use IP geolocation to restrict access. If a service blocks you despite being in the correct country, your ISP may be routing traffic through an international hub. Contacting your ISP to confirm your IP range's registered country is the first step. Alternatively, connecting through a VPN server in the correct country resolves most geo-restriction issues.

Email Being Rejected or Blacklisted

If outbound email from your server is being rejected, your sending IP may be on a blacklist. Use this tool to confirm the IP your mail server is sending from, then check it against major blacklist databases. You can also verify your email configuration using our email validator and confirm your domain's SPF and DKIM records with our DNS lookup tool.
