What is a Nameserver?
A server that stores DNS records and responds to DNS queries.
Detailed Explanation
Nameservers are the backbone of the DNS system. Authoritative nameservers hold the actual DNS records for domains, while recursive nameservers query other nameservers on behalf of clients. Most domains use at least two nameservers for redundancy. When you register a domain, you specify which nameservers are authoritative for it.

- •ns-1234.awsdns-12.com - Amazon Route 53 nameserver
