Your Address on the Internet
When you visit a website, your device sends a request that includes your IP address — the unique number that identifies your connection on the internet. Without it, the server would not know where to send the webpage back to.
An IPv4 address looks like this: 192.168.1.42. Four numbers separated by dots, each between 0 and 255. There are roughly 4.3 billion possible IPv4 addresses — which seemed inexhaustible when the system was designed in the 1980s but ran out years ago.
An IPv6 address looks like this: 2001:0db8:85a3:0000:0000:8a2e:0370:7334. Eight groups of four hexadecimal digits, providing approximately 340 undecillion possible addresses — enough for every atom on Earth to have its own IP address several times over.
What Your IP Address Reveals
An IP address alone reveals more than most people expect:
Approximate location. IP geolocation databases map IP ranges to geographic areas. They typically identify your city and country with reasonable accuracy. They do not reveal your street address or exact location — that requires more specific data.
Internet service provider. Your IP address identifies which ISP (Comcast, Verizon, BT, etc.) provides your connection.
Connection type. Whether you are on a residential, business, or mobile connection.
Organization. For business connections, the company name is often associated with the IP range.
Your IP address does NOT reveal your name, email, phone number, or browsing history to the websites you visit. However, combined with other tracking methods (cookies, browser fingerprinting), it can be used to build a more complete profile.
Public vs Private IP Addresses
Your public IP address is the one the internet sees. It is assigned by your ISP and shared among all devices on your home or office network. When any device in your home visits a website, the website sees the same public IP address.
Your private IP address is the one your router assigns to each device on your local network — typically in the ranges 192.168.x.x, 10.x.x.x, or 172.16-31.x.x. These addresses are only meaningful within your local network and are not visible to external websites.
Your router performs NAT (Network Address Translation), translating between your private addresses and your single public address. This is how dozens of devices share one public IP address.
Dynamic vs Static IP Addresses
Dynamic IPs change periodically — your ISP assigns a new address from their pool each time your router reconnects, or on a schedule. Most home connections use dynamic IPs.
Static IPs never change. They are typically used for servers, VPNs, and business connections that need to be consistently reachable at the same address.
VPNs and IP Privacy
A VPN (Virtual Private Network) routes your internet traffic through a server in a different location. Websites see the VPN server's IP address instead of yours. This changes your apparent location and hides your real IP address.
This is not a complete privacy solution — VPN providers can log your activity, and other tracking methods (cookies, browser fingerprinting) still work. But it prevents the simple IP-based location tracking that would otherwise be possible.
How to Use the Toobits IP Lookup Tool
The tool displays your current public IP address, approximate geographic location, ISP, and connection details. You can also enter any IP address to look up its geographic and network information. All lookups are performed in your browser — no additional data about you is collected or stored.
