Everything About IP Addresses

Understand how IP addresses work, why privacy matters, and how to protect your connection.

What Is an IP Address?
An IP (Internet Protocol) address is a unique numerical label assigned to every device connected to a network. It serves two main functions: host identification and network location addressing. Think of it as your digital home address — it tells the internet where to send data so it reaches your device.
IPv4 vs IPv6
IPv4 uses 32-bit addresses (e.g. 93.184.216.34) and supports ~4.3 billion unique addresses. IPv6 uses 128-bit addresses (e.g. 2606:2800:220:1:248:1893:25c8:1946) and supports 340 undecillion addresses. The internet is gradually migrating to IPv6 to handle global device growth.
How VPNs Hide Your IP
A VPN (Virtual Private Network) encrypts your traffic and routes it through a remote server. Websites see the VPN server's IP — not yours. This masks your real location, ISP, and identity from websites, advertisers, and network-level observers. Your VPN provider, however, can still see your traffic.
Can Websites Track My IP?
Every HTTP request you make reveals your public IP to the destination server. Websites use this for analytics, geolocation, fraud detection, rate limiting, and personalisation. Combining IPs with cookies, fingerprinting, and login data creates detailed behavioral profiles across sessions.
Is My IP Dangerous?
Your IP alone is relatively low-risk — it reveals approximate location and ISP. But public exposure can enable DDoS attacks (flooding your connection), port scanning, targeted phishing, or doxxing. For high-profile individuals, gamers, and developers, IP privacy is a genuine security concern.
How to Change My IP
Dynamic IPs change on router restart (provided by your ISP). Use a VPN to mask your IP with a different one instantly. Tor routes traffic through multiple nodes for maximum anonymity. For a static IP change, contact your ISP. Mobile data gives a different IP than home Wi-Fi.
Public vs Private IP
Private IPs (192.168.x.x, 10.x.x.x, 172.16-31.x.x) are used inside your local network and invisible to the internet. Your router has one public IP shared by all devices on your network via NAT (Network Address Translation). Websites see your public IP, not your private device IP.
IP Security Risks
IP-based risks include geolocation tracking, ISP-level surveillance, DDoS amplification attacks, IP spoofing, and man-in-the-middle attacks on unencrypted connections. Always use HTTPS, consider a VPN on public Wi-Fi, and avoid sharing your IP with untrusted parties online.

Frequently Asked Questions

What is a public IP address?

A public IP address is the unique identifier assigned to your internet connection by your ISP. It's how websites and servers identify your device on the public internet. Unlike private IPs (used inside your home network), public IPs are globally routable.

What is the difference between IPv4 and IPv6?

IPv4 addresses use 32-bit numbers (e.g. 192.168.1.1) and support ~4.3 billion addresses. IPv6 uses 128-bit addresses (e.g. 2001:db8::1) and supports virtually unlimited addresses. IPv6 was created to solve IPv4 exhaustion. Many connections today use IPv4, but IPv6 adoption is growing rapidly.

Can websites track my IP address?

Yes. Every time you visit a website, your public IP is visible to that server. Websites can use it for analytics, fraud detection, geolocation, and rate limiting. Your ISP can also associate activity with your IP. Using a VPN masks your real IP from websites.

How does a VPN hide my IP?

A VPN routes your traffic through an encrypted tunnel to a VPN server. Websites see the VPN server's IP instead of your real IP. This prevents tracking, bypasses geo-restrictions, and protects privacy on public Wi-Fi — but your VPN provider can still see your traffic.

Is my IP address dangerous?

Your IP alone is relatively safe — it only reveals approximate location and ISP. However, combined with other data it can enable targeted attacks (DDoS), social engineering, or tracking. Keeping your IP private reduces attack surface, especially for high-profile individuals.

How do I change my IP address?

Common methods: restart your router (dynamic IPs may change), use a VPN or proxy to mask your IP, request a new IP from your ISP, or use Tor. For permanent static IPs, contact your ISP. Note: VPNs don't change your real IP — they only mask it.

What is the difference between public and private IP?

A private IP (e.g. 192.168.x.x, 10.x.x.x) is used inside your local network and is not visible on the internet. Your router's public IP is what external websites see. NAT (Network Address Translation) maps your private IP to the public one.
