Common uses
- Check A and AAAA records for a domain
- Inspect mail routing with MX records
- Review TXT records for verification and SPF values
- Confirm NS and CAA records before DNS changes
Web diagnostics workflow
- Use DNS Lookup to confirm where a hostname points
- Use WHOIS Lookup to compare registrar and nameserver data
- Use SSL Certificate Checker after DNS changes reach the right host
- Use Redirect Checker when the domain resolves but lands on the wrong URL
