What Is a Domain Name and Why Do You Need One?

A domain name is your website's address on the internet — for example, onlyfreedomain.com. Without a domain, visitors have no way to find your site. Every website needs both a domain name and web hosting to be accessible online. Domain names typically cost between $8 and $20 per year depending on the extension and registrar.

What Is DNS?

DNS stands for Domain Name System. It is essentially the phone book of the internet. When you type a domain name like google.com into your browser, DNS translates that human-readable name into the IP address (like 142.250.80.46) where the website is actually hosted. Without DNS, you would have to memorize IP addresses for every website you visit.

How Long Do DNS Changes Take?

DNS changes take time to propagate across the internet — this is called DNS propagation. Most changes take 15 minutes to 4 hours, but can take up to 48 hours in rare cases. The TTL (Time To Live) value on each record determines how long it is cached. 💡 Pro TipBefore making DNS changes, lower your TTL to 300 seconds (5 minutes) 24 hours in advance. This makes changes propagate much faster when you make them.
