DNS attacks are a type of cybercrime that takes advantage of flaws in the Domain Name System. Because the DNS system is such an essential element of the internet infrastructure while still having several security flaws, this is a severe cybersecurity risk.
DNS propagation refers to the process of updating and distributing all of the new changes and modifications that you make in your Domain Name System (DNS) to the rest of the entire network.
When you own an online business, or perhaps, you are administrating a network, you are aware that that requires a lot of adjustments on your DNS. For instance, sometimes, you have to create, delete, or modify a DNS record, or replace an IP address. Additionally, actions such as changing the TTL (time-to-live) values, redirecting your visitors to a precise subdomain, or adding an SSL certificate also require your intervention. That is just a small part of the various different changes that could appear regarding your DNS.
The CNAME record is one of the most common DNS records, and its main purpose is to point one hostname to another. The short acronym CNAME represents with “C” – canonical and with “NAME” – hostname. With this DNS record, the administrator is able to show the actual true canonical domain name.
The Domain Name System (DNS) involves different vital processes for your domain. DNS TTL or time-to-live values are your chance to set up time in your favor! This means the power of making those processes more agile!
The DNS cache is a temporary cache memory for storing DNS records of previously queried domain names. A lot of devices hold such memory mechanisms, such as DNS recursive servers, computers, tablets, mobiles, etc.
The DNS is a complicated system that serves as a global database of domain names and IP addresses. The Internet strongly relies on DNS for its existence so much that it could be impossible to imagine its functionality without it. All the DNS data is written on DNS records, but how to copy them from server to server? With DNS zone tranfer.
It’s impressive how the Internet managed to be ingrained in humans’ lives in a very short time. The 1980s look far away from here, but honestly, considering all the previous development needed for the network of networks to exist, it’s not that much. Many people can still remember their life before and after the Internet.
To understand how the Internet works, there’s no way to skip one of the most important chapters in its history: the creation of the Domain Name System (DNS).
The DNS infrastructure is really helping the experience of Internet surfing pleasant and easy. One of the main responsible participants is the recursive DNS server. So let’s explain a little more about it and its role in the complex DNS process.
DNS records are an essential part of managing a DNS. Every one of them has a specific and very important functionality. To achieve a perfectly working DNS, it is crucial to know what is their main purpose. Here we have 5 most commonly used DNS records that are good to know for a start. Let’s see which are they and what they do!
