About Your IP Address

What Is the Difference Between Public and Private IP Address

The IP address that you see in the lookup tool is your public IP address and is different from the one that you see on your device. Your router assigns a private IP address to every device connected to it and forms a local network.

The private IP address allows the router to know about your device and where to send back the data.

On the other hand, a public IP address is your ISP’s address that connects you to the internet. It’s what a website sees when you connect to it.

IPv4 vs. IPv6 Comparison

The Internet Protocol Version 4 (IPv4) is the mainstream protocol in use today, but it has been succeeded by IPv6. As a 32-bit address, IPv4 cannot handle the rapidly growing number of devices in the world with its roughly 4 billion unique IP addresses.

IPv6 is the newer protocol that can support up to 340 undecillion IP addresses. It is more than enough to fulfill the growing new for new IP addresses on the internet.

What is Data Retention?

Data retention is the practice of recording and storing data for a specified period of time. In countries like the United States, ISPs are legally bound to record web activities of users and store them for signals intelligence.

It is a breach of privacy. And data retention mixed with heavy censorship can lead to fines or even imprisonment in authoritarian regimes like North Korea and China.

A VPN should be part of your overall digital privacy strategy. It encrypts internet traffic, preventing data retention in any region.

Why Do You Need IP/DNS Leak Protection?

VPN creates a tunnel between the client and the VPN server. Data is encrypted and the client’s IP address is spoofed during an active VPN session. But if the VPN is not configured properly or does not consider the limits of the operating system, it may leak the DNS queries to the ISP or expose your IP address on the internet.

FastestVPN features IP/DNS leak protection so that your identity remains protected at every turn.
