A CNAME lookup is a type of DNS lookup that is used to find the canonical name associated with a domain name. A CNAME record is a type of DNS record that points to another domain name. This can prove convenient when running multiple services from a single IP address.
This tool allows you to check CNAME records of any public domain without any hassle.

A CNAME record, or Canonical Name record, is a type of DNS record that points to another domain name. CNAME records are often used to create subdomains, such as www.example.com. When a user types in the address www.example.com, their computer will first contact a DNS server to find the IP address for that domain. The DNS server will then return the IP address for example.com, which is the domain that the CNAME record points to.
CNAME records cannot be used to point to an IP address, so they cannot be used to create the main domain for a website. However, they can be used to create subdomains, which can be used for different purposes, such as hosting a website or providing email service.
The Domain Name System (DNS) is a hierarchical naming system for computers, services, and other resources connected to the Internet or a private network. It associates various information with domain names assigned to each of the participants. Most prominently, it translates easily memorised domain names to the numerical IP addresses needed for locating and identifying computer services and devices with the underlying network protocols.
DNS is a distributed system, which means that the DNS database is stored on multiple servers across the Internet. This makes it more reliable than a centralised system, as it is less likely to be affected by a single point of failure.
A DNS record is a type of resource record that is stored in the Domain Name System (DNS). DNS records contain information about a domain name, such as its IP address, mail servers, and other properties.
DNS records are an important part of the Domain Name System. They allow users to easily access websites and other resources by using domain names. DNS records also provide other important functions, such as providing information about resources, caching DNS information, load balancing, and security.
