By IP Address

Let's learn how to set the allowlist or blocklist with IP addresses!

What is IP?

The Internet Protocol (IP) is the network layer communications protocol in the Internet protocol suite for relaying datagrams across network boundaries.

And an IP address refers to the unique numerical label assigned to each device connected to a network. It serves as a means to identify and locate devices within a network or on the internet. (more details on Wikipedia)

Why do we need an IP allowlist / blocklist?

IP addresses play a crucial role in security measures such as access control lists. By filtering or allowing specific IP addresses, network administrators can control which devices or networks are granted access to certain resources or services.

By blocking or allowing specific domains or IP addresses, you can enhance security. For example, you can prevent endpoint access from malicious users, hackers, or unauthorized individuals, thus mitigating the risk of depleting your endpoint usage due to unauthorized access.


It's important to note that you cannot solely rely on IP limitation for security. Implementing additional security measures, such as Json Web Token(JWT), is crucial for comprehensive protection.
