Most sites have a server that takes care of its DNS. In most cases, two DNS servers are configured on your router and/or your computer to connect your ISP via DHCP. You may configure two in case the primary server fails. If there was a problem connecting to the primary server your computer will automatically switch to the secondary server.
A DNS lookup is normally a super-fast process with a split-second turnaround to query, locate and deliver a website. Once the lookup is complete, the client computer is connected to the destination server freeing the DNS server up to deal with its next request.
It’s most likely your domain is using your ISP’s default DNS servers. However, you don’t have to. There are plenty of third-party DNS servers which may provide you with faster DNS resolves. Speed is an essential part of SEO since the time to connect to a web page is a ranking factor for Google. Experts recommend opting for reliable hosting with good speed and uptime capabilities to guarantee your website is readily viewable for your visitors.
