DNS Record Types (A, AAAA, CNAME, MX, TXT)

DNS record types are the individual entries in a domain's zone that tell the DNS where to send different kinds of traffic. The common ones are A (maps a name to an IPv4 IP address), AAAA (IPv6), CNAME (aliases one name to another), MX (routes email), and TXT (free-form text used for SPF, DKIM, and domain verification). These records are published by the nameservers you delegate a domain to, and they are what actually make a website load or mail deliver. Tokenizing a domain leaves all of this untouched: the records keep resolving normally while ownership and transfer move to a wallet-controlled on-chain layer.
