Domain Registration General

What is a domain name system (DNS) and how does it work?

DNS is the internet's phone book — it translates human-readable domain names (yourdomain.com) into IP addresses (203.0.113.5) that computers use to find servers. DNS query flow: 1) You type yourdomain.com in browser. 2) Browser checks local DNS cache (fast, if cached). 3) If not cached, queries your ISP's resolver. 4) ISP resolver queries root nameservers (.com, .in authoritative servers). 5) Root servers direct to authoritative nameservers (ns1.connectquest.in for Connect Quest-hosted domains). 6) Connect Quest nameserver returns A record IP. 7) Browser connects to that IP — your website loads. This entire process takes 1-100ms. DNS record types: A (domain to IPv4), AAAA (domain to IPv6), CNAME (alias), MX (email routing), TXT (verification and SPF), NS (nameserver delegation). DNS TTL (Time to Live) controls how long resolvers cache records — lower TTL means faster propagation of changes but more DNS queries. Manage DNS for your domains at connectquest.co.in.
