DNS Lookup Tool
Instantly query any DNS record type for any domain. A, AAAA, MX, TXT, CNAME, NS and more — real-time results, no account required.
Frequently Asked Questions
A DNS lookup queries the Domain Name System to translate a human-readable domain name (like infinium.tools) into its associated DNS records — IP addresses, mail servers, name servers, and more. Browsers use DNS lookups automatically every time you visit a website.
You can query A records (IPv4 addresses), AAAA records (IPv6), MX records (mail servers), TXT records (verification and SPF/DKIM), CNAME records (aliases), NS records (name servers), SOA records (zone authority), and CAA records (certificate authority authorization).
DNS results can vary based on your location, your ISP's resolver, DNS propagation delays (changes can take up to 48 hours to spread globally), and DNS caching. Our tool queries authoritative nameservers directly for the most accurate results.
Use our DNS Lookup tool and compare the returned IP address with your new server IP. If they match, propagation is complete for that location. DNS propagation typically takes 15 minutes to 48 hours depending on the TTL value of your records.
DNS propagation typically takes 24-48 hours after making changes. Use InfiniUm Tools DNS Lookup to query multiple record types. If you see the old value, DNS has not propagated yet. Check A records first, then MX if you changed mail settings. TTL values shown in results indicate how long records are cached.
DNS changes take time to propagate globally due to TTL (Time To Live) caching. If you recently changed a record with a high TTL (e.g. 86400 seconds = 24 hours), resolvers cache the old value until the TTL expires. Lower your TTL before making changes next time, and wait 24-48 hours for full global propagation.
