In networking and data transmission, RTT (Round-Trip Time) is a critical metric that plays a significant role in the performance and efficiency of Internet communication. In today’s article, we will explain in detail what it is, its importance, and how it affects data transmission. Whether you’re a network administrator, IT professional, or simply curious about how the internet works, understanding it can provide valuable insights into optimizing your online experience. So, without further ado, let’s begin!

What is RTT?

Round-Trip Time (RTT) refers to the duration it takes for a data packet to travel from the source to the destination and back again. This measurement includes the time taken for the packet to be sent to the destination, the time taken for the acknowledgement of receipt to be sent back to the source, and any processing delays along the way.

DNS Propagation: Why It’s Important and How to Make It as Smooth as Possible

When it comes to managing websites or online services, you might have come across the term “DNS propagation.” While it sounds technical and intimidating, understanding it is crucial for anyone involved in website management or domain changes. In this blog post, we will explore what it is, why it’s important, and provide tips on how to make the process as smooth as possible.

What is DNS Propagation?

DNS stands for Domain Name System, and it acts as the internet’s address book, translating user-friendly domain names (like www.example.com) into IP addresses (like 192.168.0.1) that computers understand. When you type a domain name into your browser, your computer queries DNS servers to find the corresponding IP address, allowing you to access the desired website.

DNS propagation, in simple terms, is the time it takes for these changes in DNS records to spread across the internet after any modifications are made. These changes could include registering a new domain, updating DNS settings, or moving a website to a different hosting provider. During propagation, DNS records are updated and cached on DNS servers worldwide, and this process can take some time to complete fully.

Currently, requesting a website seems the easiest thing for users, no matter their geographical location. But the process for this task to be successfully executed is complex. Many actors get involved in the Domain Name System (DNS) scene for users in the world to navigate the Internet easily. Today, we are introducing Recursive DNS servers.

What do Recursive DNS Servers do?

Recursive DNS servers, also called DNS resolvers, are the type of servers that get DNS queries from users and have the responsibility of resolving them by searching for the necessary DNS records in the DNS namespace.

Let me show you a very simple way to improve your website’swebsite’s reliability – Anycast DNS. You can have multiple DNS servers with the same IP address and speed up your domain resolution greatly. Here is how.

Why should you care about DNS?

DNS is the system that makes it easy for all of us to use the Internet. It translates the domain names to their IP addresses. That way, it distributes queries to the right places. For example, if you search for Google.com, your browser will have the task of using DNS to search for the correct DNS server and find the IP address of Google so that you can connect to it. In a traditional scenario, a single Primary DNS server will answer all queries for a domain name. But you can improve that by having multiple servers which can answer the query. So here comes the Anycast DNS.

CDN is an abbreviation for Content Delivery Network, and it refers to a large network of servers located in various geographical locations. The fundamental goal of these servers is to cover a large area and respond quickly to potential users’ requests. The required information, such as photos, video, and code, is stored in the cache memory of each server. They also want to be as close to the users as possible. As a result, the service is better and faster. Furthermore, the CDN has the additional benefit of load balancing. As a result, the performance of the primary server is improved, and the strain on it is reduced.

What is the SSHFP record?

A Secure Shell Fingerprint (SSHFP) record is a resource record that specifies the SSH keys connected with a host/ domain name. In addition, this provides remote connection log and networking services over an untrusted channel. When a public key is not identified, we use the Secure Shell Fingerprint record. Additionally, it will be kept locally and used for connection validation in the future.
