Nameserver (NS Record)

A nameserver is a server that answers DNS queries for a domain, and the NS records at a domain's registry declare which nameservers are authoritative for it. When you point a domain at a DNS host (Cloudflare, Route 53, your registrar's own DNS), you are setting its nameservers; those servers then publish the record types — A, MX, TXT, and the rest — that route traffic and mail. Tokenizing a domain does not change this layer: the nameservers and their records keep working exactly as before, while ownership and transfer move to a wallet-controlled on-chain layer on top.
