live DNS resolverDNSweepFree DNS lookup with ASN, geolocation, anycast detection, and SPF analysisMulti-resolverCompare answers from Cloudflare, Google, and the zone's authoritative servers.17 record typesA, AAAA, MX, TXT, NS, SOA, CAA, SRV, DNSKEY, DS, TLSA, NAPTR, HTTPS, SVCB, SSHFP, PTR, CNAME.No trackingQueries run server-side. No accounts, no analytics.DNS lookup with full IP attributionDNSweep resolves a domain across Cloudflare (1.1.1.1), Google (8.8.8.8), and the zone's own authoritative name servers, then shows the answers side by side so resolver-level differences are obvious. It covers every common record type (A, AAAA, CNAME, MX, NS, TXT, SOA) plus CAA, SRV, DNSKEY, DS, TLSA, NAPTR, HTTPS, SVCB, SSHFP, and PTR.Every A and AAAA record is annotated with its ASN and owning organization, geolocation, and whether the IP belongs to an anycast network. DNSweep also identifies the CDN, WAF, or cloud provider in front of an IP, so you can tell at a glance whether a host sits behind Cloudflare, Fastly, Akamai, AWS, and others.Check propagation in real timeAfter a DNS change, the propagation checker streams results as a record rolls out across authoritative name servers, 14 public DoH resolvers, and 23 countries. Answers are grouped into variants, so you can see exactly which parts of the world still hold a cached value.Built for debugging, not trackingLookups run server-side. No accounts, no analytics, no upsells. DNSweep parses SPF records into a clear pass, softfail, hardfail, and neutral breakdown with recursive include resolution, and also surfaces whois, subdomains, reverse IP, HTTP security headers, and multi-region uptime.See how it compares to other DNS tools, or jump to a popular lookup: cloudflare.com, google.com, github.com, or wikipedia.org.
