In today’s connected world, having remote access to personal or business networks is a necessity. Whether you’re hosting a website, managing a home automation system, or accessing files remotely, having a stable, accessible IP address is critical. This is where Dynamic DNS (DDNS) comes into play. It allows devices with frequently changing IP addresses to be easily accessible through a consistent domain name. In this blog post, we’ll dive deep into DDNS, its functionality, and its benefits, helping you understand why it could be a valuable tool for your network management needs.

TXT record – Definition and details
Today we will explore the TXT record. It is an exciting and helpful DNS record type. So, first, we will define its purpose and then move to the importance of implementing it. And the final stage of our article is to review what the TXT record looks like (its structure). So, without further ado, let’s get down to business.
Definition of TXT record
A TXT record is a DNS record that exposes text data to sources outside of your domain. Many TXT records can be found in a top-level domain name. Human-readable facts on servers, networks, databases, and other IT information are frequent in TXT records. Sender Policy Framework (SPF), DomainKeys (DK), and DomainKeys Identified E-mail (DKIM) are some of the applications for TXT records.
How does DNSSEC work?
If you are browsing for what DNSSEC is and how it works, you came to the right place. In this article, we will focus on its primary purpose and its benefits. So, let’s explain it.
What does DNSSEC mean?
DNSSEC is a collection of protocols and specifications for securing the Domain Name System and its associated activities. From lookups to data transmission, it’s all here.
Authenticated denial of existence, cryptographic authentication of DNS information, and information integrity are all provided by these enhancements to DNS resolvers.
The Internet Engineering Task Force (IETF) invented it. Because the Domain Name System was not designed with security in mind from the start. Different vulnerabilities were discovered early on in its utilization. After that, DNSSEC was created. The creators picked the extension format for this system to make it easier to integrate with the existing DNS infrastructure.
TTL: How does it work?
What is TTL?
Time-to-live, or for short just TTL, is a value that limits the amount of time or the number of hops that a data packet is set up for being alive. That could be on a network or in the cache memory. Once that time expires, either the number of hops reaches their limit, the data packets won’t be available anymore.
