Why does DNS cache matter & How to flush it?

Data exchange happens at a lightning pace. Every time you type a website address into your browser, it doesn’t immediately connect you to the requested website. Instead, a series of behind-the-scenes processes take place, one of which involves DNS (Domain Name System) resolution. DNS acts like a directory, translating human-readable domain names into IP addresses that computers can understand. But what role does DNS cache play in this process, why does it matter, and how can you flush it when necessary?

What is DNS Cache?

DNS cache is a mechanism employed by computers and networking devices to store recently accessed DNS information locally. When you visit a website for the first time, your computer sends a request to a DNS resolver to translate the domain name into an IP address. Once the resolver obtains the IP address, it stores it in its cache for future use. Next visits to the same website skip the DNS resolution process and directly access the IP address from the cache, speeding up the browsing experience.

4 Popular DNS Attacks and How to Avoid Them

DNS attacks are significant threats to businesses and individuals, potentially leading to service disruptions, data breaches, and unauthorized access to sensitive information. Understanding these attacks and implementing appropriate preventive measures is crucial in safeguarding against potential cyber threats.

What are DNS attacks?

DNS attacks exploit vulnerabilities within the Domain Name System to disrupt, intercept, or manipulate DNS traffic, thereby compromising the integrity and availability of online services. These attacks can manifest in various forms, ranging from simple DNS spoofing to sophisticated Distributed Denial of Service (DDoS) attacks.

DNS attacks not only undermine the reliability of internet services but also jeopardize user privacy and security by redirecting legitimate traffic to malicious destinations or intercepting sensitive data transmissions.

DNSSEC – Why is it so beneficial?

Speaking bluntly, the Domain Name System (DNS) is the backbone of today’s big Internet. But such important creation got born without a security system. Without DNS, there’s no Internet, at least not in the comfortable way we know it now. Would you trust the Internet knowing that its backbone operates without security? Well, from here, you have a clue to know why DNSSEC is so beneficial. But we can go deeper!

DNSSEC definition

DNSSEC is how the security extensions to the DNS are named. It means Domain Name System Security Extensions. This group of security solutions was created to authenticate and protect DNS traffic. It’s the security layer of the DNS and the Internet that is needed to work safer. It adds cryptographic signatures to DNS records.

Secondary DNS: Explained for Beginners

Secondary DNS is a crucial part of any digital infrastructure and provides essential benefits such as improved uptime, faster response times, and added security. In this article, we’ll look at, how to set it up, and some best practices for managing it.

Secondary DNS: What is it?

Secondary DNS is an integral part of any digital infrastructure and one that administrators often overlook. In a nutshell, it provides an added layer of redundancy and failover capabilities to DNS services, providing extra protection against connection and uptime problems associated with the primary DNS services. In addition, this service allows DNS queries to be split across multiple servers, meaning that if one connection fails, the other (secondary) DNS still responds. This ensures more reliable service for your users and can help prevent extended outages or packet loss due to DNS-related issues. This service allows for better redundancy, uptime, and more reliable service than relying on a single DNS server.

What does DNS Spoofing stand for?

What does “DNS Spoofing” refer to?

DNS Spoofing, commonly referred to as DNS cache poisoning, is a cyberattack and phishing. Instead of directing you to the page you wanted to visit, it leverages the DNS servers to give your web browser the incorrect IP address. Due to this, DNS inquiries frequently return false positives, directing visitors away from safe websites and toward risky ones designed to steal personal information or distribute malware.
