DNS records, short for Domain Name System records, are crucial components of the Internet infrastructure. DNS is a mapping system connecting domain names to their respective IP addresses. DNS records provide essential information such as the authoritative name servers for a domain, mail server addresses, and other details necessary for internet services to function correctly. Common types of DNS records include A records (mapping domain to IP address), MX records (specifying mail server information), CNAME records (aliasing one domain to another), and TXT records (providing arbitrary text information). These records are fundamental in ensuring proper communication and accessibility across the internet. Learn more about the various different DNS record types!
