Amazon Web Services, or AWS, is one of the most reliable and popular cloud computing platforms out there. It provides a plethora of functionalities such as content delivery, computing power, and database storage to help you grow and scale.
With cyber threats increasing in volume and sophistication, having a robust security strategy is essential to minimize your exposure and risk. Keeping this in mind, IP whitelisting is an effective method to increase security and control access to your cloud environment.
In this guide, we’re not only going to talk about IP whitelisting but also highlight how to whitelist an IP address on AWS. Get the utmost online security of your website with PureVPN.
IP Address – A Brief Definition
Every Internet-enabled device – like computer, smartphone, printer, and camera – is assigned a unique numerical label called the IP address or Internet Protocol address, which serves both as a host identifier and locator. There are two versions of the Internet Protocol (IP), namely Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6).
IPv4 is the most widely used and defines IP addresses in a 32-bit format, whereas IPv6 is fairly new and defines IP addresses in a 128-bit format. Moreover, IP addresses are allocated in two ways: dynamically or statically. Dynamic IP addresses remain constant every time you connect to the Internet, while static IP addresses stay the same.

IP Whitelisting Explained
In simple terms, IP whitelisting is a feature that allows you to control and limit access based on a list of specified IP addresses. It’s commonly used by administrators to prevent unauthorized parties from accessing corporate digital assets. While IP blacklisting also serves the same purpose, the way it does so is different – i.e. by identifying and blocking access to specified IP addresses.
The Benefits of IP Whitelisting
From a security point of view, it’s easier and much more efficient to put a complete ban on everything, and only let in a selected few. When just trusted users have the ability to gain access, the odds of an intruder getting inside are significantly reduced. IP whitelisting also enables you to ensure secure remote access and mitigates the risks that come with BYOD.

Why You Need PureVPN’s Dedicated IP?
IP whitelisting is a great security measure for controlling access to your AWS resources, but it works best when you use static IP addresses. In this way, you won’t have to update IP addresses for whitelisting every time your IP changes.
Fortunately, PureVPN offers an extensive pool of squeaky clean dedicated (static) IPs from eight countries, including Hong Kong, Germany, Singapore, United Kingdom, Australia, Malta, United States, and Canada.
