Nameserver
ELI5 — The Vibe Check

Real Talk
A nameserver is a DNS server that holds authoritative records for a specific domain zone. When configured at your registrar (e.g., ns1.example.com), all DNS queries for that domain are routed to it. Hosting providers and services like Cloudflare often provide nameservers.
