For example, if you’re hosting a WordPress site and your host’s “wait” time is substantial (greater than a second or so), this could really be slowing down your website. Further, factors such as queuing delays can complicate access to the Domain Name System servers.Īnother factor that can impact DNS resolution time is the quality of your web hosting. Each hop translates into a network iteration to reach the address, thereby increasing access times for each DNS name server. When DNS servers are geographically located far from the host server, the requesting computer has to perform multiple network hops to reach the DNS server. Moreover, increases in latency can have major impacts on the user experience of a website. TTL can vary from days to weeks to years. Specifically, Time-to-Live (TTL) refers to the period of time in which a DNS name is cached before it expires on your computer. However, things get complicated when the DNS name server is located halfway around the world, or if the DNS name server cache has expired.

If the DNS server information is available in your browser cache, or if the DNS name server is available at a location close to you, then the process is relatively simple. Why is DNS Resolution Time Important for your Website?ĭNS resolution time affects the time it takes for host server to receive and process a request for a webpage, also known as latency. They are the first connections made by your web server, once a user types in your website URL.

Distributed DNS name servers, thus, become necessary to manage these processes. A large number of IP addresses translate into an even larger number of interconnections and DNS processes between clients and servers. The IPv6 protocol dramatically multiplies the number of IP addresses available in the ecosystem.

Because the number of IP addresses is fast running out, IPv6 was introduced. There are 4.7 billion possible addresses available in IPv4. Most people don’t connect to servers via these IP addresses, therefore the DNS process is extremely valuable.

The DNS servers are responsible for the interface between machines and humans because they convert human-designated domain names into into their corresponding machine IP addresses (ex.
