Frequently Asked Questions
What is my IP address?
Your IP address is a unique numerical label assigned to your device by your Internet Service Provider (ISP). It identifies your device on the internet and allows servers to send data back to you. This tool detects your current public IP address in real time.
What is the difference between IPv4 and IPv6?
IPv4 uses a 32-bit address written as four groups of numbers (e.g., 203.0.113.1) and supports about 4.3 billion unique addresses. IPv6 uses a 128-bit hexadecimal address (e.g., 2001:db8::1) and supports virtually unlimited addresses. IPv6 was created because the internet ran out of available IPv4 addresses.
Can someone find my location from my IP address?
IP geolocation can identify your approximate city and region — usually within 25–50 miles — but cannot reveal your exact street address. The accuracy depends on how your ISP assigns IP ranges. Your ISP, however, knows exactly which customer is using which IP at any given time.
How do I hide my IP address?
Use a VPN (Virtual Private Network) to mask your real IP. A VPN routes your traffic through a server in another location, so websites and services see the VPN server's IP address instead of yours. Tor and proxy servers also hide your IP but with different trade-offs in speed and anonymity.
What does my ISP see?
Your ISP can see your public IP address, the domains you visit, the timing and volume of data transfers, and your device identifiers. Without a VPN, all your unencrypted traffic is visible. Even with HTTPS, ISPs can see which domains you visit (not the content).
Why does my location show the wrong city?
IP geolocation maps IP ranges to cities based on where your ISP registered them. ISPs often register large IP blocks at their headquarters or regional data centers, causing the displayed city to differ from your actual location. This is normal and doesn't mean the tool is broken.
What is an ASN?
An Autonomous System Number (ASN) is a unique identifier assigned to a network managed by a single organization under a unified routing policy. ISPs, hosting companies, and large enterprises each have their own ASN. For example, Google's ASN is AS15169, Cloudflare's is AS13335.
Does this tool save my IP address?
No. Your IP is detected in real time using your browser and is not stored or logged. No account or registration is required to use this tool.
Understanding IP Addresses
What Is an IP Address?
An IP (Internet Protocol) address is a numerical label assigned to every device connected to the internet. It works like a postal address — enabling servers worldwide to send data back to the correct device. Without an IP address, two-way communication on the internet would be impossible.
IPv4 vs IPv6: What's the Difference?
IPv4 is the fourth version of the Internet Protocol and the most widely used. It uses 32-bit addresses written as four decimal numbers separated by periods (e.g., 203.0.113.45). IPv4 supports approximately 4.3 billion unique addresses — a number that was exhausted globally in 2011 as internet-connected devices multiplied.
IPv6 is the successor, using 128-bit addresses written in hexadecimal (e.g., 2001:0db8:85a3::8a2e:0370:7334). It supports 340 undecillion unique addresses — more than enough to assign a unique IP to every atom on Earth. Many ISPs now provide both an IPv4 and IPv6 address to each customer, called dual-stack connectivity.
Public vs Private IP Addresses
Your public IP is the address your ISP assigns to your router — it's what the outside world sees when you browse the web. Your private IP is the address your router assigns to each device on your local network (e.g., 192.168.1.10) and is not visible outside your home or office network. This tool shows your public IP address.
Dynamic vs Static IP Addresses
Most home internet connections use a dynamic IP — one that can change each time you reconnect, or periodically at your ISP's discretion. Businesses often pay for a static IP that never changes, which is required for hosting servers, VPNs, or remote desktop services. If you reconnect and your IP has changed from a previous visit, that's normal.
What Is IP Geolocation?
IP geolocation maps an IP address to a physical location using databases maintained by organizations like MaxMind, IP2Location, and others. These databases are built from ISP registration records, network routing data, and user-submitted corrections. Accuracy varies: country-level lookups are typically 99% accurate; city-level lookups are accurate to within 25–50 miles for most residential IPs. Corporate or VPN IPs often show the location of a data center rather than the actual user's location.
What Is an ISP?
An ISP (Internet Service Provider) is the company that provides your internet connection — examples include Comcast, AT&T, BT, Deutsche Telekom, and Verizon. Your ISP owns the block of IP addresses assigned to your connection and can associate any public IP to a specific customer account, date, and time.
What Is an ASN?
An Autonomous System Number (ASN) is a globally unique identifier assigned to a network that operates under a single organization's routing policy. ISPs, large tech companies, universities, and hosting providers each control one or more ASNs. Routing protocols like BGP use ASNs to exchange routing information between autonomous systems. Knowing the ASN behind an IP reveals which organization operates the network.
What Is Reverse DNS?
Reverse DNS (rDNS) maps an IP address back to a hostname — the opposite of a standard DNS query. For example, the IP 8.8.8.8 resolves to dns.google. ISPs and organizations configure reverse DNS records for their IP blocks. Many email servers use reverse DNS checks as a spam-filtering mechanism — IPs without proper rDNS records are often rejected.
Protecting Your IP Address
While your IP address alone doesn't reveal your name or address, it can be used to approximate your location or trace you via your ISP. To increase privacy:
- Use a VPN — routes traffic through an encrypted server, hiding your real IP from websites and trackers.
- Use Tor — routes traffic through multiple relays for strong anonymity, though at reduced speed.
- Use a proxy — cheaper than a VPN but usually unencrypted and less reliable for privacy.
No tool provides 100% anonymity — advanced fingerprinting techniques can still identify browsers even without knowing the IP. A quality VPN combined with good browser hygiene provides strong practical privacy for most users.
