Domain Name System

Like a telephone directory, a domain name system (DNS) bridges the gap between humans and computers by linking domain names to their respective Internet Protocol (IP) addresses.

You want to go to the website, so you enter the domain name in the address bar of your web browser. What you are doing here is sending a DNS request.

The function of a domain nameserver is to store all DNS records for a domain name. Every time someone sends a query about your domain name, the nameserver returns the information corresponding to your domain name, allowing them to find your website.

In practice, nameserver addresses often point a domain name to a hosting account through DNS services.

This action is unnecessary if you have purchased a domain name from a hosting provider. But it must be done if the domain registrar is not the same as your hosting provider.

For example, if you host a website at Elementor Cloud but own a domain from Namecheap, you will have to change the DNS address to Elementor Cloud. Only then will the domain name be connected to the website.

Domain Name System Facts

  1. Domain names are converted into IP addresses by the DNS (Domain Name System), a vital component of the internet. Following are some statistics and information about DNS:
  2. There are more than 330 million domain names registered as of 2021.
  3. The typical resolution time for a DNS query is 20–120 milliseconds.
  4. Every day, billions of requests are resolved by DNS, which is the foundation of the internet’s infrastructure.
  5. One of the most recent developments in DNS is the use of DNS-over-HTTPS (DoH), which encrypts DNS requests and boosts privacy and security.
  6. OpenDNS, Cloudflare, and Google Public DNS are a few well-known DNS service providers.
  7. A number of companies, including Verisign, ICANN, and NASA, run the DNS root servers.
  8. According to the most recent reports, many organizations are taking steps to defend their DNS infrastructure due to the possibility of DNS manipulation and cyberattacks.
  9. Additionally gaining popularity is the DNS-over-TLS (DoT) protocol, which offers similar privacy advantages as DoH while remaining compatible with conventional DNS infrastructure.
