About DNS Lookup

What is DNS?

DNS (Domain Name System) is like the internet's phone book. It translates human-readable domain names (like google.com) into IP addresses (like 142.250.185.46) that computers use to communicate with each other.

DNS Record Types

  • A Record: Maps domain to IPv4 address (e.g., 192.0.2.1)
  • AAAA Record: Maps domain to IPv6 address
  • CNAME Record: Alias pointing to another domain
  • MX Record: Mail server for the domain
  • TXT Record: Text information (SPF, DKIM, verification)
  • NS Record: Authoritative name servers
  • SOA Record: Start of Authority information
  • PTR Record: Reverse DNS lookup (IP to domain)

What is TTL?

TTL (Time To Live) indicates how long (in seconds) a DNS record should be cached before requesting fresh data. Lower TTL means more frequent updates but more DNS queries.

DNS-over-HTTPS (DoH)

This tool uses Cloudflare's DNS-over-HTTPS service, which encrypts DNS queries for better privacy and security. Traditional DNS queries are sent in plain text, making them vulnerable to eavesdropping and manipulation.

Use Cases

  • Verify DNS configuration after domain changes
  • Troubleshoot website connectivity issues
  • Check mail server (MX) records
  • Verify domain ownership (TXT records)
  • Find authoritative name servers
  • Debug DNS propagation

Common Examples

google.com (A)

Returns Google's IPv4 addresses

github.com (CNAME)

Shows GitHub's canonical name

gmail.com (MX)

Lists Gmail's mail servers
