RFC_5737 is a document that defines specific IP address ranges reserved for documentation and examples. These addresses are not routable on the internet, meaning they cannot be used for real-world networking. Instead, they serve as placeholders in technical documents, tutorials, and educational materials, ensuring that readers can understand concepts without using actual IP addresses.
The reserved ranges include 192.0.2.0/24, 198.51.100.0/24, and 203.0.113.0/24. By using these addresses, authors can provide clear examples without the risk of conflicting with real IP addresses. This helps maintain clarity and prevents confusion for those learning about networking.
