Deep dive into Dynamic DNS

No Comments DNS , , , , , , , , , , ,

The Domain Name System (DNS) is a foundational component of internet infrastructure, translating human-readable domain names into IP addresses. Traditional DNS setups, however, assume static IP addresses for domain names, which can be a limitation in modern, dynamic network environments. This is where Dynamic DNS (DDNS) comes into play. DDNS allows for the automatic updating of DNS records, making it possible to maintain consistent domain name to IP address mappings even when IP addresses change frequently. This blog post provides a detailed technical deep dive into Dynamic DNS, exploring its mechanisms, benefits, use cases, and implementation.

Understanding Dynamic DNS (DDNS)

Dynamic DNS (DDNS) is an extension to the standard DNS protocol, enabling the automatic update of DNS records for devices with dynamically assigned IP addresses. This is particularly useful for devices that connect to the internet through Internet Service Providers (ISPs) that frequently change the IP addresses assigned to their customers.

The Role of RTT (Round-Trip Time) in Network Efficiency

No Comments Network , , , , , ,

Round-Trip Time (RTT) is a crucial metric that often determines the efficiency and speed of our internet connections. Whether you’re streaming a video, browsing a website, or participating in a video call, it plays a significant role in your online experience. In today’s article we explain more about it, why it matters, and how it affects our daily digital interactions.

What is Round-Trip Time (RTT)?

Round-Trip Time, commonly referred to as RTT, is the measure of the time it takes for a signal to travel from the source to the destination and back again. In simpler terms, it’s the time elapsed between sending a request and receiving a response. This metric is crucial for understanding the latency in a network connection.

Imagine sending a letter to a friend and waiting for a reply. The total time it takes from sending your letter to receiving a response is analogous to RTT in networking. However, in the digital world, this process happens in milliseconds.
