DNS Record Types (A, AAAA, CNAME, MX, TXT)
The entries in a zone that map a domain to addresses and services — A, AAAA, CNAME, MX, TXT, and more.
- glossary
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.

His work sits at the intersection of naming, ownership, and the systems people use to establish identity online. That perspective makes him especially interested in the way names move between personal meaning, public recognition, and digital infrastructure.
For Namefi, Victor edits and writes about domains as durable digital identity: how names become ownable onchain assets, how tokenization changes custody and trust, and what naming can learn from the systems people use to establish identity online.
