IP Address Lookup
Instantly see your public IP address. Look up any IP for geolocation, ISP, ASN, and timezone information.
🌍 What is IP Geolocation?
IP geolocation maps an IP address to an approximate physical location using databases that track IP allocation. Accuracy varies: country is ~99% accurate, city is ~70–80%.
🕵️ VPN & Proxy Detection
VPNs replace your real IP with one from a datacenter. Geolocation will show the VPN server's location, not yours — useful for privacy but also how websites detect VPN users.
🔢 IPv4 vs IPv6
IPv4 uses 32-bit addresses (like 192.168.1.1) with ~4.3 billion possible IPs. IPv6 uses 128-bit addresses for an effectively unlimited pool. Most ISPs now support both.
IP Lookup — FAQ
Why does my IP location show the wrong city?
IP geolocation is approximate. Your ISP routes traffic through regional hubs, so the detected city may be the nearest major exchange or datacenter — not where you physically are. VPN users will see the VPN server's location.
What is an ASN?
An Autonomous System Number (ASN) identifies a network operated by a single organization under a consistent routing policy — typically an ISP, hosting company, or large enterprise. For example, AS15169 is Google's ASN.
Can websites see my IP address?
Yes — every website you visit can see your public IP. It's a fundamental part of how the internet works. To hide it, use a VPN or Tor, which replace your IP with one from their network.
What's the difference between public and private IP?
Your private IP (like 192.168.x.x) is assigned by your home router and only visible on your local network. Your public IP is assigned by your ISP and visible to the rest of the internet — this is what this tool shows.
Does this tool store my IP address?
No. 2faco has no backend and does not log or store anything. The address is fetched by your browser directly from a public IP database (ipapi.co or ipwho.is) over HTTPS, and the results are rendered locally on your device.
Why do different websites show different locations for the same IP?
Each lookup provider maintains its own geolocation database built from different sources, such as IP registries, ISP routing data, and commercial signal data. Databases are updated at different times and can disagree at the city level, especially after an ISP reallocates address blocks.
Can someone find my exact street address from my IP?
No. IP geolocation is approximate and typically resolves only to the city or region level. Public IP databases do not contain street addresses, and law enforcement generally needs a court order to an ISP to obtain subscriber information.
How to Use the IP Lookup Tool
Before you start, it helps to know what this tool does: it detects the public IP address of your current connection and, when you ask, it looks up public records about any other IP address or domain. Everything runs in your browser. The address is fetched from a public IP database over an encrypted HTTPS connection, so there is nothing to install, register for, or configure.
- Open this page. Your public IP address is detected automatically and displayed at the top of the tool card — no clicks required.
- Read the details table. Below the address you will find your approximate country, region, city, postal code, timezone, ISP or organization, and ASN. Use the copy button next to the address to save it to your clipboard.
- Look up another address. Type an IP such as
8.8.8.8or a domain name likeexample.cominto the field and press Look Up to see that address's details instead. - Check the version and flags. Notice whether the result is IPv4 or IPv6, and whether the warning badge flags the address as a possible VPN or proxy.
- Reset to your own address. Use the "Look up my IP instead" link below the input field whenever you want to return to your own connection's details.
What You Can Do With IP Details
An IP lookup is most useful when you are diagnosing something about your own connection. If you just changed networks, a quick lookup confirms what the rest of the internet sees when you connect. If you use a VPN or proxy, the same tool shows whether traffic is actually routed through the expected server — the IP and location will match the VPN provider, not your physical address.
Looking up a third-party address is useful for developers and support teams too. Checking the ASN tells you who operates a network — an ISP, a hosting company, or a corporate network — which helps you judge whether a request or sign-up really originated from the region it claims. Support teams routinely compare the location of a login attempt against where the user normally connects from.
That said, geolocation has real limits. Databases are compiled from registration records, routing tables, and partner observations, and they do not always agree with each other. A few things worth keeping in mind:
- Treat city-level results as approximate. The registered "city" is often the ISP's regional hub or data exchange, which is common for rural connections and large corporate networks.
- Don't confuse an IP with an identity. An IP identifies a connection, not a person. A single router can carry traffic for an entire household, and mobile carriers rotate IP addresses frequently, so results can change between requests.
- Exact street-level location is not possible. No public lookup can resolve an IP to a street address. Claims that they can are marketing — or worse. Precise location data is not part of the IP protocol.
