DNS Lookup Tool
Quickly resolve domain names to IP addresses. Essential for network troubleshooting, website migrations, and security analysis.
Example: example.com or https://example.com
Understanding DNS Lookups
The Domain Name System (DNS) is the phonebook of the internet. When you enter a domain name like example.com, DNS servers translate it to an IP address like 93.184.216.34 that computers use to connect.

DNS Lookup Best Practices
- Always verify DNS changes propagate globally (can take up to 48 hours)
- Check both IPv4 and IPv6 records when troubleshooting
- Use multiple DNS servers to verify results (Google 8.8.8.8, Cloudflare 1.1.1.1)
- Combine with WHOIS lookups for complete domain information
- Monitor TTL (Time-To-Live) values when planning DNS changes
