DNS records are pieces of information stored on DNS servers that link a URL to an IP address. They are text instructions that indicate the IP address associated with a domain and can provide other information as well. DNS records are essential for connecting websites to the rest of the internet and keeping the internet functioning the way consumers expect.
There are many types of DNS records, including:
- A Record: An A record (Address Record) points a domain or subdomain to an IP address.
- AAAA Record: An AAAA record (IPv6 Address Record) points a domain or subdomain to an IPv6 address.
- CNAME Record: A CNAME record (Canonical Name Record) points a domain or subdomain to another domain name.
- MX Record: An MX record (Mail Exchange Record) specifies the mail server responsible for accepting email messages on behalf of a domain name.
- TXT Record: A TXT record (Text Record) contains text information about a domain, such as SPF (Sender Policy Framework) records used to prevent email spam.
Overall, DNS records are essential for connecting domain names to IP addresses and keeping the internet functioning properly.
