Description
DNS Checker/Whois & IP Lookup is the network reference your phone has been missing. Type any hostname and instantly see the A records returned by Google, Cloudflare, Quad9, Alibaba, and your device's own resolver — side by side. Type any domain and pull live Whois data from the authoritative registry. No accounts, no signup, no fluff.
WHY MULTIPLE RESOLVERS?
Different DNS servers can return different answers for the same name. ISPs rewrite responses, CDN edges return geo-specific IPs, captive portals lie. By querying several well-known resolvers in parallel and comparing the results in one screen, you can spot DNS rewrites, debug propagation delays, and verify that your records have actually rolled out worldwide — not just in your ISP's cache.
DNS LOOKUP
- Parallel A-record queries against curated public resolvers - Includes the OS's configured local resolver for an apples-to-apples comparison - Per-server latency so you can see who answered fastest - Clear timeout / error markers when a resolver fails to respond - Recent-queries history for one-tap rerun
WHOIS
- RFC 3912 client with IANA referral for accurate TLD-to-registry handoff - Optional eTLD+1 normalisation: www.example.com is treated as example.com - Shows registrar, creation / expiry / updated timestamps, EPP status codes, and authoritative name servers - Raw response is always available for when you need the exact text
