What Is an IP Address?

An IP address (Internet Protocol address) is a unique identifier assigned to your device when it connects to the internet. It allows websites, apps, and services to communicate with your device.

IPv4 vs. IPv6

IPv4 is the most common format, consisting of four numbers (e.g., 192.168.1.1). IPv6 is a newer format designed to solve address exhaustion, using longer alphanumeric strings (e.g., 2001:0db8:85a3::8a2e:0370:7334).

Why Does My IP Change?

Your IP address may change regularly if your Internet Service Provider (ISP) assigns dynamic IPs. Businesses or advanced users may request a static IP, which doesn't change.

IP Geolocation and Accuracy

Websites use your IP address to estimate your physical location. However, this method isn't always accurate — geolocation is based on public records from ISPs and may reflect the nearest city or data center.

Protecting Your Online Privacy

• Use a VPN: A Virtual Private Network hides your real IP and encrypts your traffic.
• Use Tor: The Tor network routes your traffic through multiple nodes for anonymity.
• Use a Proxy: Proxies relay your traffic but may not encrypt it.

Keep in mind that free tools often come with privacy trade-offs. Always research your tools.

Security Risks of IP Exposure

Your IP address can potentially reveal:

• Your approximate location
• Your ISP and network type
• Whether you're on a corporate, residential, or mobile network

While most users aren’t directly targeted via their IP address, it can be used in combination with other data for tracking or attacks.

Need to Check Your Internet Speed?

Run a speed test to measure your connection quality and determine if your VPN or ISP is slowing you down.

Advanced Info

• Reverse DNS Lookup: Shows the hostname assigned to your IP (used by email servers and some analytics tools).
• ASN (Autonomous System Number): Identifies the ISP or organization that owns the IP range.
• Browser Details: Web servers can often detect your browser, OS, screen size, and more via user-agent strings.

Public vs. Private IP Addresses

Public IPs are routable on the internet and assigned by your ISP. Private IPs are used within local networks (e.g., 192.168.x.x, 10.x.x.x) and are not visible outside your home or office.
