A Records (also known as Address Records) are used to map a domain name to an IPv4 address. This is the most common type of DNS record and is essential for directing traffic to the correct server. When a user types a domain name into their web browser, the DNS system uses A Records to find the corresponding IP address and connect the user to the correct website.

CNAME Records (Canonical Name Records) are used to create an alias for a domain name. This allows multiple domain names to point to the same IP address without needing separate A Records for each one. For example, if you have a website at www.example.com, you can create a CNAME record for example.com that points to www.example.com. This way, both domain names will direct users to the same website.

CNAME Records are often used for subdomains, such as blog.example.com, which can point to a different server or service while still being part of the main domain.

CNAME Records are also useful for pointing to third-party services, such as content delivery networks (CDNs) or cloud hosting providers.

AAAA Records (also known as Quad A Records) are similar to A Records but are used to map a domain name to an IPv6 address. As the internet transitions to IPv6, AAAA Records are becoming increasingly important for ensuring that websites can be accessed using the newer IP address format. When a user types a domain name into their web browser, the DNS system uses AAAA Records to find the corresponding IPv6 address and connect the user to the correct website.

AAAA Records are essential for ensuring that websites can be accessed using the newer IP address format.

MX Records (Mail Exchange Records) are used to specify the mail servers responsible for receiving email on behalf of a domain. Each MX Record contains a priority value and the hostname of the mail server. When an email is sent to an address at a domain, the DNS system uses MX Records to determine which mail server should receive the email. The priority value indicates the order in which mail servers should be used, with lower values being preferred over higher ones. For example, if a domain has two MX Records with priorities 10 and 20, the mail server with priority 10 will be used first. If that server is unavailable, the server with priority 20 will be used as a backup.

TXT Records (Text Records) are used to store arbitrary text data associated with a domain name. They can be used for various purposes, such as providing information about the domain, verifying domain ownership, or implementing security measures like SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail). TXT Records are often used in conjunction with email services to help prevent spam and phishing attacks.

WHOIS is a query and response protocol used to obtain information about the registered owner of a domain name. It provides details such as the registrant's name, organization, contact information, and the domain's registration and expiration dates. WHOIS records are maintained by domain registrars and can be accessed through various WHOIS lookup tools. WHOIS information can be useful for verifying the legitimacy of a domain, identifying the owner of a website, or resolving disputes related to domain ownership.
