Domain Name System

Domain Name System (DNS) is a hierarchical decentralized system that maps domain names to IP addresses. It is the internet’s equivalent of a phone book, mapping human-readable domain names to IP addresses.

DNS resolution

DNS resolution translates the domain name into its server IP address. You need a site’s IP address to know where it’s on the Internet.

The four DNS Servers work together (in a chain) to convert a domain name to its IP address, enabling the requested web resource to load on the user screen.

DNS Process

How DNS Works When You Enter a URL in Your Browser (SEO-Friendly Explanation)

When you type https://xyz.com into your web browser, the DNS lookup process begins:

  1. Your browser sends a DNS query to a DNS resolver (recursive DNS server), usually provided by your Internet Service Provider (ISP).

  2. The DNS resolver checks its DNS cache to see if it already has the IP address for the domain.

    • If the record is found in the cache, it quickly returns the result to your device.

  3. If the record is not cached, the resolver contacts the Root DNS Servers, which store information about Top-Level Domains (TLDs) like .com, .net, and .org.

  4. The root servers reply with the correct TLD DNS server responsible for the domain’s extension (e.g., .com).

  5. The resolver then queries the TLD name servers, which provide the location of the authoritative DNS servers for the specific domain.

  6. The authoritative DNS server sends back the accurate DNS records, including the domain’s IP address.

  7. The resolver stores (caches) these updated DNS records and sends them to your computer, allowing your browser to load the website quickly and efficiently.

DNS propagation

DNS propagation is the time DNS changes take to be updated across the internet over the globe. It can take up to 48 hours to propagate worldwide. Use our Global DNS Propagation Checker for free to get a quick report on your DNS propagation status.

DNS not propagating

The ISPs across the world have different caching levels. The DNS client or the server may cache the information of the DNS records in its DNS cache. That information is temporarily cached, and DNS servers will go for the updated DNS information when TTL (Time to Live) expires.

Domain name doesn’t exist?

The DNS server will return a name error, also known as an NXDomain response (for a non-existent domain), to symbolize that the query’s domain name does not exist.
