Example Use Cases
- Verify DNS records are properly configured after adding a new subdomain
- Check MX records before switching email providers to avoid mail loss
- Debug propagation delays by comparing records across multiple nameservers
- Confirm TXT records (SPF, DKIM, DMARC) are published for email authentication
Common Issues
Propagation delays: Record changes can take 5 minutes to 48 hours to propagate globally depending on TTL settings. Lower TTL before planned changes.
Missing trailing dot: Some DNS providers
require a trailing dot for fully qualified domain names in
record values. Always include it (e.g.,
example.com.).
