Question 1

What is IPv4?

Accepted Answer

IPv4 (Internet Protocol version 4) is the fourth version of the Internet Protocol and is still the most widely used addressing system on the internet. It uses 32-bit addresses, typically written as four numbers separated by dots, such as 192.168.1.1. Because the number of available IPv4 addresses is limited, many internet providers now also support IPv6.

Question 2

What is IPv6?

Accepted Answer

IPv6 (Internet Protocol version 6) is the latest version of the Internet Protocol. It uses 128-bit addresses, providing an enormous number of unique IP addresses to support the continued growth of the internet. IPv6 also improves routing efficiency, scalability, and network performance.

Question 3

What is the difference between IPv4 and IPv6?

Accepted Answer

The main difference is the address space. IPv4 supports approximately 4.3 billion unique addresses, while IPv6 supports an almost unlimited number of addresses. IPv6 also introduces improvements in routing, efficiency, and overall network scalability.

Question 4

What is Dual Stack?

Accepted Answer

Dual Stack means your internet connection supports both IPv4 and IPv6 simultaneously. Your device can communicate using either protocol depending on the website or online service you access.

Question 5

How can I find my IP address?

Accepted Answer

Simply open this page. Your browser automatically detects your public IPv4 and IPv6 addresses (when available) and displays additional information such as your country, city, Internet Service Provider (ISP), ASN, timezone, and connection details.

Question 6

Why does my IP address change?

Accepted Answer

Most Internet Service Providers assign dynamic IP addresses. This means your public IP address may change after restarting your modem, reconnecting to the internet, or after a lease renewal performed automatically by your ISP.

Question 7

What is CGNAT?

Accepted Answer

Carrier-Grade NAT (CGNAT) is a technology used by Internet Service Providers to allow multiple customers to share the same public IPv4 address. This helps conserve IPv4 addresses but may prevent users from opening ports or hosting services directly from their home network.

Question 8

What is an ASN?

Accepted Answer

ASN stands for Autonomous System Number. It is a unique identifier assigned to an internet network operated by an Internet Service Provider, cloud provider, or large organization. ASNs are used to exchange routing information across the global internet.

Question 9

Can my IP address reveal my exact location?

Accepted Answer

No. A public IP address usually identifies only an approximate geographic location, such as your city, region, or country. It does not reveal your exact home address or your real-time GPS location.

Question 10

Can someone track me using my IP address?

Accepted Answer

An IP address can reveal general information such as your country, region, city, and Internet Service Provider, but it does not expose your personal identity. Websites and online services use IP addresses for communication, while your ISP is generally the only organization capable of linking an IP address to an individual subscriber.

Question 11

Does using a VPN change my IP address?

Accepted Answer

Yes. When you connect to a Virtual Private Network (VPN), your internet traffic is routed through the VPN provider's servers. As a result, websites see the VPN server's public IP address instead of your own.

Question 12

Is my IP address private?

Accepted Answer

Your public IP address is visible to the websites and online services you visit. However, it does not include personal information such as your name, email address, or physical home address.
