DNS Record

A DNS record is a piece of information published in the Domain Name System to help other systems locate or verify services associated with a domain. Different record types serve different purposes: A and AAAA records can point names toward IP addresses, MX records identify mail routing destinations, and TXT records often carry verification or policy information. A handyman website might move to a new host while keeping email with a separate provider, making careful DNS changes important. DNS settings do not contain the website's content itself. A wrong record can disrupt a website or email, so changes should be documented and checked against the instructions of the relevant provider.
