Domain & IP Lookup

Look up A, AAAA, MX, NS, TXT, CNAME records for a domain, or geolocation and ASN for an IP. Disclosed third-party APIs.

Calls third-party services (Google DNS, ipapi.co) on lookup. See the warning on the tool above.

External services: This tool calls dns.google (Google's DNS-over-HTTPS resolver) and ipapi.co to look up DNS records and IP geolocation. Your search query and IP are visible to those services. Click "Look up" to proceed.
Enter a domain or IP and click Look up.

About this tool

Look up DNS records for a domain (A, AAAA, MX, NS, TXT, CNAME) or geolocation and ASN information for an IP address. Useful when diagnosing email problems, verifying SPF/DKIM records, finding a server's hosting provider, or just confirming where a website is hosted.

What you'll see

For a domain, you'll get its A records (IPv4 addresses), AAAA records (IPv6), MX records (mail servers), NS records (authoritative nameservers), and TXT records (often containing SPF, DKIM, domain verification strings, etc.). The first A record is also geolocated.

For an IP address, you'll get its geolocation, ASN, ISP, and reverse-DNS hostname if one is set.

Privacy note

This tool routes through two external services because browser JavaScript can't directly perform DNS queries or WHOIS lookups — those need a server-side resolver. We use:

  • Google DNS-over-HTTPS (dns.google) for DNS records. Google sees your query.
  • ipapi.co for geolocation of IPs. The service sees the IP you're asking about.

Neither sees more than the query itself. Digitools doesn't proxy anything — calls go directly from your browser to those services.

Frequently asked questions

Why no WHOIS data (registrar, registration date)?
WHOIS requires a server-side resolver — browsers can't talk to WHOIS port 43. Adding it would mean running a backend service for it, which breaks the "no backend" architecture. If you need WHOIS, command-line whois example.com or sites like who.is have you covered.
What's an SPF record / why does it matter?
SPF (Sender Policy Framework) is a TXT record listing IPs allowed to send email for your domain. If you're troubleshooting why mail you sent isn't arriving, an SPF mismatch is a common cause.
Why are MX records shown with numbers?
The number is "priority" — lower means try first. Mail servers attempt delivery in priority order, falling back to higher numbers if the lower-priority ones aren't responding.
Can I look up records other than the standard ones?
This tool returns A, AAAA, MX, NS, TXT, and CNAME. For SRV, CAA, DS, DNSKEY, and other records, use dig on the command line.
