A Complete Guide to DNS Records
A, AAAA, CNAME, MX, TXT, and NS records explained in plain language with practical examples.
A records point a hostname to an IPv4 address. AAAA records do the same for IPv6. CNAME records alias one hostname to another hostname.
MX records control mail delivery. TXT records are commonly used for verification, SPF, DKIM, and DMARC. NS records delegate a zone to specific nameservers.
When troubleshooting DNS, always check the hostname, record type, exact value, and expected TTL before assuming propagation is the problem.
