Question 1

What is an IP address?

Accepted Answer

An IP address is a unique identifier assigned to every device connected to a network. IPv4 uses 32-bit addresses (e.g. 192.168.1.1) while IPv6 uses 128-bit addresses (e.g. 2001:db8::1); both protocols are in use today.

Question 2

What can be found from an IP address?

Accepted Answer

You can find an approximate geolocation (usually down to the city level), the ISP, timezone and AS information — but never an exact home address or personal identity.

Question 3

How do I hide my IP address?

Accepted Answer

A VPN is the most common approach: your traffic travels through an encrypted tunnel and the outside world sees the VPN server's IP instead of yours. Choose a reputable provider and be wary of free VPNs.

Question 4

Why does my IP address change?

Accepted Answer

Most home broadband connections use dynamic IPs, so each connection or router restart may assign a different address. A static IP requires a request to your ISP.

Question 5

How can I protect my IP privacy?

Accepted Answer

Avoid sensitive operations on public WiFi, use HTTPS, enable your system firewall, don't share your IP casually, clear browser cookies regularly, and use a VPN when needed.
