DNS Propagation: DNS Lookup
Dorian Borovina
Changed a DNS record? DNS Propagation shows in seconds whether public DNS resolvers already return the new value. Enter a domain, pick a record type and compare the answers of eight resolvers side by side, with response times, TTLs and how fresh each cached answer is. Built for webmasters, developers and IT admins moving a website, switching mail providers or changing nameservers. Propagation check: - Queries AdGuard, AliDNS, Cloudflare, DNS.SB, DNSPod, Google, NextDNS and RethinkDNS at the same time over DNS-over-HTTPS - One clear status: all resolvers agree, mismatch, or error - Record types: A, AAAA, CNAME, MX, TXT, NS, SOA and SRV - Response time and TTL for every resolver, fastest first TTL analysis: - Queries the domain's own nameservers directly for the original TTL - Shows how long each resolver has cached the answer and how fresh it still is, color-coded - See at a glance when an old record will expire everywhere History and gestures: - Your last 50 lookups, grouped by day with their status - Tap to expand a lookup, long press for all details - Swipe right to check a domain again, swipe left to delete it - Double-tap results to copy them, including the TTL analysis Settings: - Turn individual resolvers on or off - Request timeout from 1 to 30 seconds - TTL analysis on or off - Light, Dark and System appearance - Works on iPhone and iPad, with a sidebar on iPad
