Free DNS Lookup
Look up public DNS records for a domain, including IP addresses, mail servers, name servers, aliases, TXT records, and SPF email policies. No account required.
Enter only the domain, such as example.com. Do not include https:// or a page path. SPF lookup searches TXT records for a value beginning with v=spf1. Results come from Google's public DNS resolver and may differ from other resolvers.
