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.
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.comor 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
digon the command line.
