Question 1

What is an IP address and how does it work?

Accepted Answer

An IP (Internet Protocol) address is a unique numerical label assigned to every device connected to a computer network that uses the Internet Protocol for communication. It serves two primary functions: network interface identification and location addressing, enabling servers to route web pages, emails, and data streams directly to your device.

Question 2

What is the difference between IPv4 and IPv6?

Accepted Answer

IPv4 addresses are 32-bit numbers formatted as four decimal octets separated by periods (e.g., 192.0.2.1), supporting approximately 4.3 billion unique addresses. IPv6 uses 128-bit addresses formatted as eight groups of hexadecimal digits separated by colons (e.g., 2001:0db8:85a3::8a2e:0370:7334), providing virtually unlimited address space along with improved routing and security.

Question 3

How accurate is IP geolocation?

Accepted Answer

IP geolocation identifies the approximate physical location of an internet-connected device. At the country level, accuracy is typically 95% to 99%. At the region or state level, it ranges from 80% to 90%, and at the city level, accuracy is between 50% to 80%. Geolocation maps to your Internet Service Provider's (ISP) routing hub, not your exact residential address.

Question 4

What is the difference between a public and private IP address?

Accepted Answer

A public IP address is assigned by your ISP and is globally unique across the entire internet. It is the visible address remote servers see when you browse websites. A private IP address (such as 192.168.x.x or 10.x.x.x) is assigned by your local Wi-Fi router to distinguish devices within your home or office network and is never routed on the public internet.

Question 5

Can someone discover my personal identity from my IP address?

Accepted Answer

No. An IP address by itself does not reveal your name, street address, email, or phone number to the general public or websites. It only reveals your network provider, approximate city, and routing coordinates. Only your ISP possesses subscriber records linking an IP to a person, which require court subpoenas to disclose.

Question 6

How can I hide or change my IP address?

Accepted Answer

You can mask or change your public IP address using a Virtual Private Network (VPN), a secure proxy server, or the Tor network. When connected to a VPN, your traffic is encrypted and routed through an intermediary server, replacing your actual public IP with the VPN server's IP.
