DNS lookups and IP analysis
Query real DNS records for any domain through Cloudflare's 1.1.1.1 resolver, and analyze IPv4/IPv6 addresses down to their class, range, and network details.
Network tools query real DNS records through Cloudflare's 1.1.1.1 resolver and analyze IP addresses at the protocol level. You can look up A, AAAA, MX, CNAME, TXT, and NS records for any domain, verify mail-server configuration, or check whether an IP address is public, private, or reserved. All queries run server-side through Cloudflare's DNS-over-HTTPS endpoint, so results are live and authoritative. Network engineers, sysadmins, and DevOps teams use these tools for troubleshooting, migration planning, and security verification.
Every tool below is free, runs instantly in your browser, and never uploads your data.
Queries hit Cloudflare's live DNS-over-HTTPS endpoint in real time, so results reflect current authoritative data.
No — IP analysis here is purely mathematical (class, range, public/private). Geolocation is never performed.
