DNS Management India 2026: Complete DNS Configuration for Indian Domains

Understanding DNS: How It Works

When a visitor's browser loads your website, the DNS resolution process involves multiple servers working together. The browser first queries a DNS resolver (typically provided by the visitor's ISP or a public service like Google DNS 8.8.8.8). The resolver queries root nameservers, then TLD nameservers (.com, .in), then your domain's authoritative nameservers, which finally return the IP address for your domain. This entire process typically takes 20-100 milliseconds for a cached lookup, or up to 300 milliseconds for a first-time lookup from a cold cache.

DNS Record Types

A Record: Maps a domain name to an IPv4 address (e.g., 192.168.1.1). The A record is the most fundamental DNS record — it tells the world where your website is hosted. Example: yourdomain.in with an A record pointing to 203.0.113.15.

AAAA Record: Maps a domain name to an IPv6 address. As IPv6 adoption increases in India (particularly on JIO Fiber and Airtel Xstream Fiber), AAAA records become more relevant for future-proofing your DNS configuration.

CNAME Record: Creates an alias from one domain name to another. CNAMEs are commonly used for subdomains — pointing www.yourdomain.in to yourdomain.in so both load the same website. CNAMEs cannot be set on the root domain (yourdomain.in) on most DNS providers.

MX Record: Specifies the mail servers responsible for receiving email for your domain. MX records have a priority value — lower numbers have higher priority, and mail servers are tried in order until delivery succeeds. Example: mail.yourdomain.in with MX priority 10.

TXT Record: Stores arbitrary text data for verification and security purposes. TXT records are used for SPF (Sender Policy Framework) email authentication, DKIM (DomainKeys Identified Mail) email signing, and DMARC (Domain-based Message Authentication, Reporting and Conformance) policy declaration.

NS Record: Delegates a DNS zone to use a specific set of authoritative nameservers. NS records are set at the registrar level and determine which servers are authoritative for your domain.

Common DNS Configurations

Pointing domain to Hostinger: Set the A record for your root domain (yourdomain.in) to Hostinger's server IP address, found in your hPanel welcome email. Set a CNAME for www.yourdomain.in pointing to yourdomain.in.

Setting up Google Workspace email: Add MX records provided by Google (aspmx.l.google.com, alt1.aspmx.l.google.com, etc.) with decreasing priority values (1, 5, 10, 20, 50).

Adding Cloudflare CDN: Change your domain's nameservers (NS records) to Cloudflare's nameservers (ns1.cloudflare.com, ns2.cloudflare.com). Then add an A record pointing to your hosting server's IP, and enable the orange Cloudflare proxy.

DNS Propagation in India

DNS changes typically propagate within 2-6 hours for most Indian ISPs (JIO, Airtel, BSNL). However, TTL (Time to Live) values set on your DNS records can extend this — if your old records have a 24-hour TTL and you make a change, ISP DNS caches may honor the old cached record for up to 24 hours. Setting TTL to 300 seconds (5 minutes) before making changes accelerates propagation. Indian DNS propagation can occasionally take 24-48 hours for enterprise connections with stricter caching policies.
