What is a public IP address?
Your public IP address (Internet Protocol) is the unique identifier assigned to your internet connection by your ISP. Unlike a private IP — used within your local network — your public IP is visible to any server on the internet and is essential for online communication to work.
The most widely used protocol, with 32-bit addresses in the format 192.168.0.1. It supports about 4 billion unique addresses — a number that has been exhausted with the growth of the internet.
The next-generation protocol, with 128-bit addresses (e.g. 2001:db8::1). It offers a virtually unlimited number of addresses and is already active in much of the world.
Reverse DNS (rDNS) translates an IP address back into a domain name. Used by mail servers, security systems and network diagnostics to identify the origin of a connection.
Frequently asked questions
What is my public IP used for?+
Your public IP identifies your connection on the internet, allowing servers to know where to send responses to your requests — such as web pages, videos and emails.
Can someone track me by my IP?+
An IP can reveal your approximate location (city/state) and ISP name, but not your exact address. Services like websites and servers log IPs, which can be accessed by legal authorities.
What is reverse DNS and why does it appear?+
Reverse DNS maps your IP to a domain name. On home connections it's common to see your ISP name (e.g. dynamic.isp.net). On servers it's essential for email authentication.
Why do I have two IPs (IPv4 and IPv6)?+
Many ISPs now provide both protocols simultaneously — called dual-stack. IPv6 was created to replace IPv4, whose addresses have been exhausted.
How can I hide my IP?+
The most common ways are a VPN (Virtual Private Network), a Proxy or the Tor network. Each offers a different level of privacy, speed and complexity.
What is IP geolocation?+
It's the technique of estimating a device's geographic location based on its IP. Accuracy varies: it usually gets the country and city right, but rarely the exact address.
Does my IP change over time?+
It depends on your ISP. Dynamic IPs change periodically or when you reconnect your router. Static IPs are permanent and usually a paid service.
