Understanding domains

When you buy a domain, you can choose a root domain or a subdomain for your LMS.

To help you understand some of the terminologies, we’ve provided you with definitions of common terms about domains.

A record

An A record is a DNS setting that checks if a domain name has a specific IP address associated with it. In this case, you want your A record to point to the Learnsby IP address. Other terms: Address record, host record

CNAME record

A CNAME record is a DNS setting that points your subdomains to another domain name. In this case, you want your CNAME record to point to your Learnsby-hosted domain by using yourdomain.learnsby.com Other terms: CNAME resource record, Alias


Domain Name Systems (DNS) is a database of domain names. Every domain has its own DNS entry. It organizes domain names and translates them from words (for example, learnsby.com) to numbers (for example, Learsby’s IP address is This lets you visit a website without having to memorize its IP address. Typically, this process works quickly in the background, but when you connect your domain with your Learnsby LMS you might need to change your DNS settings Other terms: DNS records, DNS settings, resource records, DNS file zone

Domain name

A domain name is the address that people use to visit your website on the internet. It appears in the address bar of your web browser and is linked to a specific IP address. Other terms: domain

Domain provider

A domain provider is a company that will register your domain name for you. Typically, you purchase a domain on a subscription basis and you pay a regular fee to your domain provider to keep using your domain name. Other terms: domain registrar, domain host

IP address

An IP address is a unique string of numbers that specifies the location of a computer or device on the internet and distinguishes it from others. It is required for one computer to communicate with another over the internet. Other terms: Internet Protocol address

Root domain

A root domain is the domain name that you purchase from your domain provider. It does not contain a prefix, such as www., but has a top-level domain (TLD) extension like .com, .org, or .net. An example of a root domain is learnsby.com. Other terms: base domain, top-level domain and second-level domain

SSL certificate

An SSL certificate is a security protocol that creates a safe connection between a server and a browser to keep your information secure. In Learnsby, your LMS has an SSL certificate to encrypt your LMS content and publish it securely using HTTPS instead of HTTP. Other terms: Secure Sockets Layer


A subdomain is a subset of your root domain that you see as a prefix to your root domain. For example, in the URL help.learnsby.com, learnsby.com is the root domain and help. is the subdomain. You can use subdomains to organize your website and make it easier for visitors to find the information that they’re looking for.

Top-level and second-level domains

A top-level domain (TLD) and a second-level domain are components of the root domain that give hierarchy to the domain structure. For example, in the root domain learnsby.com, the top-level domain is .com and the second-level domain is learnsby.
