DNS (Domain Name System) is often called the "phonebook of the internet." It translates human-readable domain names like google.com into numerical IP addresses like 142.250.185.206 that computers use to communicate. Every time you type a URL into your browser, DNS resolution happens within milliseconds to find the correct server.
The DNS system works through a hierarchy of servers. When you type a domain name, your ISP's recursive resolver (DNS server) first checks its cache. If not found, it queries root nameservers → TLD nameservers (for .com, .in, .org) → authoritative nameservers for your specific domain. This entire process typically completes in 20-100 milliseconds.
Our free DNS lookup tool queries authoritative nameservers directly, giving you the most accurate and up-to-date DNS records — not cached data from your ISP. This is crucial when you are migrating hosting, setting up email, or troubleshooting DNS-related issues.
For Indian website owners, DNS configuration is particularly important for several reasons:
When switching from one Indian hosting provider to another (e.g., from BigRock to Hostinger India), DNS records must be updated correctly to avoid downtime. Use our DNS lookup tool to verify changes before and after migration.
Properly configured MX records are essential for business emails. Indian businesses using Google Workspace or Microsoft 365 need correct MX records. Our tool helps verify them instantly.
Some SSL certificates (especially wildcard certificates) require CNAME or TXT record verification through your DNS provider. Our DNS checker helps you verify these records are in place.
When transferring a domain between registrars like GoDaddy India, Namecheap, or Uniregistry, DNS records must remain intact throughout the process to avoid service interruption.
Indian websites increasingly use Cloudflare (free DDoS protection) or AWS CloudFront. CDN setup requires adding CNAME records or changing NS records — mistakes cause major outages.
Before launching email marketing campaigns or SMS links, verify your domain's TXT records (for SPF, DKIM, DMARC) to ensure emails land in inboxes, not spam folders.
DNS records are stored in DNS zone files on authoritative nameservers. Each record type serves a specific purpose. Our free DNS checker looks up all the important record types:
Maps a domain name to an IPv4 address (e.g., 192.168.1.1). This is the most fundamental DNS record — every domain needs at least one A record pointing to a server IP address. A records are required for web hosting.
Maps a domain name to an IPv6 address (e.g., 2001:0db8:85a3::8a2e:0370:7334). As IPv4 addresses run out, IPv6 adoption is growing in India. AAAA records work alongside A records for dual-stack support.
Creates an alias from one domain name to another. Common uses: redirecting www.example.com to example.com, or pointing cdn.example.com to a Cloudflare distribution. CNAMEs cannot coexist with other records at the same node.
Specifies the mail servers responsible for accepting emails for your domain. Priority values (0-100) determine which server to try first — lower numbers have higher priority. Essential for business email with Google Workspace or Zoho Mail in India.
Holds arbitrary text data. Most importantly, TXT records store SPF (Sender Policy Framework) records for email authentication, DKIM (DomainKeys Identified Mail) signatures, and DMARC policies. Required for reliable email delivery.
Delegates a DNS zone to use specific authoritative nameservers. NS records tell the internet which servers are authoritative for your domain. Typically 2-4 NS records per domain. Your domain registrar or hosting provider provides these.
Start of Authority record contains administrative information about the DNS zone: primary nameserver, admin email, serial number (used to track zone changes), and refresh/retry/expire timings. Critical for DNS zone management.
Specifies the location (hostname and port) of servers for specific services like LDAP, SIP, XMPP, or Microsoft Exchange ActiveSync. Less common but important for enterprise applications and some messaging platforms.
Certification Authority Authorization restricts which Certificate Authorities can issue SSL certificates for your domain. CAA records add security by preventing unauthorized CAs from issuing certificates. Becoming more widely used as browser support improves.
Using our free DNS checker is straightforward and provides instant results:
Type the domain name you want to check (e.g., 'google.com', 'amazon.in', 'flipkart.com'). Include the TLD (.com, .in, .org) — partial domains won't resolve correctly.
Our tool automatically checks all major record types: A, AAAA, MX, TXT, NS, CNAME, SOA, and SRV. You can filter to specific record types using the tabs in the results.
Results appear within seconds, showing all DNS records currently published on the domain's authoritative nameservers. Each record shows its type, value, TTL, and priority (for MX records).
Compare records before and after making changes to verify DNS updates. Useful when migrating hosting, changing email providers, or setting up SSL certificates. Records not showing? Try the Advanced tab.
When you run a DNS lookup on our tool, here is what each field means:
The DNS record type (A, MX, TXT, etc.). Each type serves a specific function in how your domain routes traffic and email.
The actual data stored in the record. For A records, this is an IP address. For MX records, this is a mail server hostname. For TXT records, this is the text content (SPF, DKIM, etc.).
How long (in seconds) the record can be cached by DNS resolvers before it needs to be refreshed. Lower TTL (300-3600 seconds) means faster propagation but more queries to your nameserver. Higher TTL (86400+) means less load but slower updates.
For MX records, a lower number means higher priority. If the highest priority mail server is unavailable, mail is sent to the next lowest priority server. Standard priorities range from 0 to 100.
The authoritative nameserver that returned these results. Different nameservers may have slightly different cached data during propagation periods.
Fix: After changing hosting providers, DNS changes can take 24-72 hours to fully propagate globally. Use our DNS lookup tool to check if your new hosting IP is showing up on authoritative nameservers. Lower TTL values (300 seconds) before migrating for faster propagation.
Fix: Check your MX records — they should point to your email provider's servers (Google, Microsoft, Zoho). Verify TXT records include proper SPF, DKIM, and DMARC entries. Use our free DNS checker to confirm all email-related records are correct.
Fix: Many wildcard SSL issuers verify domain ownership via DNS CNAME or TXT records. Check that the required record is published using our tool. Some DNS providers have propagation delays — wait 5-30 minutes after adding verification records.
Fix: Clear your local DNS cache (run 'ipconfig /flushdns' on Windows, 'sudo dscacheutil -flushcache' on Mac). Try checking from a mobile network or VPN to test from a different resolver. Use our DNS checker to compare results from multiple viewpoints.
Fix: Add an A record pointing www to your server IP, OR a CNAME pointing www to the apex domain (@). Both approaches work — CNAME is simpler, A record is more reliable for performance.
Fix: Before transferring a .in domain (popular with Indian registrars like .in Registry, BigRock), ensure your domain is unlocked and has valid nameservers. Some registrars require SOA serial numbers to match before allowing transfers.
DNS propagation is the time it takes for DNS changes to spread from your authoritative nameservers to all the recursive DNS servers (like your ISP's DNS) around the world. When you change your A record to point to a new hosting provider, this change doesn't happen instantly everywhere — it cascades through the global DNS infrastructure.
The propagation time depends on the TTL (Time To Live) value set on your DNS records. TTL tells resolvers how long to cache the record before asking again. If your A record has a TTL of 86400 seconds (24 hours), it can take up to 24 hours for all resolvers to see the new IP after a change.
Before migrating hosting, reduce your TTL to 300-3600 seconds (5 minutes to 1 hour) at least 24 hours before the migration. This ensures that once you update your DNS records, the changes propagate quickly. After the migration is confirmed, you can increase the TTL back to 86400+ seconds for better performance.
Our free DNS propagation checker queries authoritative nameservers directly, so it shows the true current DNS data — not cached data. This makes it the most reliable way to verify your DNS changes have been published.
Use reputable DNS providers — Cloudflare (free), Amazon Route 53, or your registrar's DNS. Avoid cheap registrars with unstable DNS infrastructure.
Set TTL values strategically: use low TTL (300-3600s) before planned changes, high TTL (86400+) for stable records after changes
Maintain at least 2 nameservers (most registrars provide 2 by default) for redundancy
Always configure SPF, DKIM, and DMARC TXT records before launching email marketing — this is mandatory for Indian bulk email senders to avoid spam classification
If using Google Workspace or Microsoft 365 for business email in India, verify MX records immediately after setup using our free DNS checker
For high-traffic Indian e-commerce sites, consider premium DNS services with global PoPs and DDoS protection (Cloudflare, Akamai, Fastly)
Use DNSSEC (DNS Security Extensions) if your registrar supports it — this cryptographically signs DNS data to prevent spoofing attacks
Document all DNS changes with timestamps — maintain a spreadsheet or log of when records were changed and why
Before transferring domain registrars, verify SOA serial numbers match between current and new registrar's DNS systems
Run our free DNS lookup tool to audit your DNS configuration at least quarterly and after any hosting or provider changes
Yes, our DNS lookup tool is 100% free with no registration required. Query as many domains as you need, anytime. We query authoritative nameservers directly for the most accurate results.
Our tool retrieves A, AAAA, MX, TXT, NS, CNAME, SOA, SRV, and CAA records. You can filter results by record type using the tabs in the results section.
Your ISP's DNS server caches records and may show old (stale) data during propagation periods. Our tool queries authoritative nameservers directly, showing the true current DNS configuration.
DNS propagation is global and not region-specific. Typically 2-48 hours, though it can occasionally take up to 72 hours. Indian ISPs (Airtel, Jio, BSNL, ACT) all cache DNS based on the TTL values set on your records.
Cloudflare (free) is excellent for most Indian websites — they have server locations in Mumbai and Chennai. For enterprise sites requiring 100% uptime SLA, Amazon Route 53 or Azure DNS are solid paid options with global Anycast networks.
Check your SPF, DKIM, and DMARC TXT records. Also verify that port 25 (SMTP) is not blocked by your network or hosting provider — some Indian ISPs and cloud providers block port 25 by default. Try alternate SMTP ports like 587 or 465.
Yes, our DNS checker works for all TLDs including .in, .co.in, .org.in, .net.in, .com, .org, .io, .co, and hundreds of other extensions. Simply enter the full domain name.
DNSSEC adds cryptographic signatures to DNS data to prevent DNS spoofing and cache poisoning attacks. If your registrar (.in Registry for Indian domains, or registrars like GoDaddy India for international TLDs) supports DNSSEC, enable it — it adds a layer of security at no cost.
