What is DNS?
DNS, the Domain Name System, is the internet's address book. It turns a domain name into the server address a browser needs to load your site.
DNS stands for Domain Name System. It works like the internet's address book. People type a name like yourbusiness.com, but computers find each other by number (an IP address). DNS looks up the name and hands back the right number, so the browser knows which server to ask for your website. The same system tells other mail servers where to deliver your email. Your DNS settings live with a DNS host, which may be your registrar, your web host or a separate service.
Why it matters for your business: If your DNS settings are wrong or missing, your website and your email can stop working even though nothing is wrong with the site itself.
