Let’s get back to the idea that a domain name is equal to an IP address (in it’s simplest form). How does a domain name know what IP address to route to when you enter a domain name? The answer is DNS or Domain Name System. Think of DNS like a telephone operator's switchboard or more technically a database of domains and their corresponding IP addresses. So when you type in a domain name it hits the name server and resolves an IP address to send the request to. When your webmaster says “Point your DNS’s A record to {some IP address}” it may sound confusing, but that just means you need to update it to point to the new A record of the web server where your website is hosted. An “A” record corresponds to your website and your “MX” record points to your email. Please note that it is best practice to ensure your DNS stays hosted with where you purchased your domain name. If you allow your webmaster to move your DNS to them you lose control and it can cause issues later on.
