Explanation and definition of DNS cache
A DNS cache is a temporary cache memory used by DNS resolvers and other devices to store data. The DNS records that were initially applied to the domain names that were searched are kept in memory. These records contain information such as domain names’ IP addresses (IPv4 or IPv6), details about their email servers, services, authentication, verification information, and more. The DNS cache will save all of the data. However, as previously said, it will only last briefly because each DNS record has a TTL (Time to Live) value.
It is significant to notice that the DNS cache will momentarily contain all of the records for the different domain names. This is because the administrator sets the TTL (Time to Live) value, which determines how long it will last.
Users’ DNS queries can get faster responses thanks to this method, which also aids in effective resource optimization.
DNS monitoring is the topic of our post today. It is critical to know it if you want to improve your security. So, let’s not waste any more time on idle chatter and instead focus on enjoying this adventure.
TTL is really obligatory if you are using the Domain Name System. It is like an expiration date for DNS records. How it works, and can you check it, we will see later. Let’s start.
Choosing a quality DNS provider is an important decision. If your next plan is to conquer the Internet, you definitely need DNS infrastructure to land in the cyber world. The DNS will be the foundation to build your business. That’s why you have to make an informed choice.
There are different aspects to consider, but here you have 5 tips that can guide your search!
1. Always check the servers’ location
As a business owner, you must clearly know your target market. While looking for a DNS provider, the objective must be that you could be as close to your clients as possible. To have DNS servers close to your market accelerates essential factors for your domain like the DNS resolution, loading time, etc. For example, if you are interested only in the European market, don’t waste time with a provider that offers a solid network all around the USA.
