Frequently Asked Questions

What is a CNAME used for?

CNAME or Canonical Name is a type of DNS or Domain Name System record that is used to create an alternate name for a domain or subdomain. The main aim of CNAME Records is to associate one domain name with another domain. CNAME is especially beneficial when you want to point multiple domain names to the same IP address.

Is a CNAME an IP address?

No, a CNAME (Canonical Name) is not an IP address. It is a type of DNS (Domain Name System) record that is used to create an alias or an alternate name for a domain. It is often used to map one domain name to another. On the other hand, an IP address (Internet Protocol address) is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. IP addresses are used to identify and locate devices on a network.

Is CNAME the same as DNS?

DNS refers to the entire system and protocol used to translate human-readable domain names (such as example.com) into IP addresses (such as 192.0.2.1) that computers understand. DNS includes various types of records, including CNAME, A, AAAA, MX, TXT, and more. A CNAME record is a specific type of DNS record. It is used to create an alias or an alternate name for a domain. When a DNS resolver encounters a CNAME record, it replaces the original domain name with the canonical name specified in the CNAME record and then continues the DNS resolution process.
