TTL in DNS and Networking: Key Concepts

When discussing networking and the Domain Name System (DNS), one of the most critical yet often overlooked parameters is the Time to Live (TTL). Understanding TTL is essential for network administrators, IT professionals, and anyone interested in optimizing network performance and reliability. This blog post delves into the key concepts of TTL, its significance in DNS and networking, and best practices for its configuration.
