How this service works
Purchase: DNS Lookup
Output
Returns DNS records for the queried domain, including record types (A, AAAA, MX, CNAME, TXT, NS, etc.), values, and TTL information.
Example use cases
Verify email domain MX records
“Can you check the MX records for acmecorp.com? I need to confirm their mail servers are set up correctly before we try sending them emails.”
Confirm domain nameserver configuration
“Look up the nameservers for mybusiness.io — I just transferred the domain and want to make sure the NS records have propagated to the new registrar.”
Check TXT records for domain ownership
“Pull up the TXT records for startup.dev so I can verify the Google Search Console and SPF records are in place.”
