Domain Name System is defined as the shortened form of the words DNS, which stands for Domain Name System. We wouldn't be wrong to say that DNS is the telephone directory of the internet world. Web browsers connect using IP addresses and translate DNS domain names into IP addresses, allowing browsers to easily load internet resources.
DNS delegates the responsibility of assigning domain names and mapping these names to internet resources by assigning authoritative name servers for each domain. Network administrators can authorize other servers over subdomains. This mechanism provides a distributed and fault-tolerant service and is designed to avoid a single large central database.
What is DNS that facilitates your work?
All computers on the internet, from servers providing content to large retail websites to your smartphone or laptop, find and communicate with each other using numbers. These numbers are known as IP addresses. When you open a web browser and go to a website, you don't have to remember and enter a long number.
Telephone directory DNS
We mentioned above that DNS is the telephone directory of the internet world, so how does this work briefly? The DNS system of the internet works like a telephone directory by managing the mapping between names and numbers. DNS servers convert name requests into IP addresses, checking which server the end-user's web browser will reach when they type a domain name. These requests are called queries.
DNS and Types of Services
Authoritative DNS: An authoritative DNS service provides an update mechanism used by developers to manage public DNS names. It then responds to DNS queries and translates domain names into IP addresses so that computers can communicate with each other. Authoritative DNS has the final authority over a domain and is responsible for providing answers to recursive DNS servers.
Recursive DNS: Clients typically do not query authoritative DNS services directly. Instead, they usually connect to another type of DNS service known as a resolver or a recursive DNS service. For example, a recursive DNS service, acts like a hotel concierge: even if it doesn't have any DNS records, it serves as an intermediary that can obtain DNS information on your behalf. If a recursive DNS has cached the DNS reference or kept it for a specific period, it responds to the DNS query by providing resource or IP information. If this is not the case, it forwards the search to one or more authoritative DNS servers to find the desired target.
How to increase website speed with DNS?
DNS may not be directly related to your internet speed, but it can significantly affect how quickly a web page appears on your computer. However, it should not affect download speeds once a connection is established. If you want to change your router's DNS servers, it may help improve your overall speed.
Changing DNS servers can speed up the time it takes to resolve a domain name, but it does not guarantee that it will speed up your overall internet connection. For example, improvements in average download speeds for streaming content or downloading large files can vary by country.
To illustrate, a DNS connection in country X may connect to websites faster, while a connection made in another country may tend to connect to websites at a slower speed. Of course, the services you use are also very important. Improving your DNS speed and performance can elevate your internet and DNS experience to higher levels with the expertise of specialized teams like PlusClouds.
To increase internet speed with DNS
Enter your router's management page and go to your advanced settings. Take note of your DNS server addresses for reference. Replace them with your recommended DNS server addresses. Your device will then be updated with these DNS servers and offer you enhanced browsing speeds.
