About this app

DNS Kit helps developers, IT professionals and website owners investigate DNS and email configuration from their phone or tablet.

DNS AND EMAIL DIAGNOSTICS
Look up A, AAAA, CNAME, MX, TXT, SOA and PTR records. Inspect SPF and DMARC, discover common DKIM selectors, and review findings with explanations. A DKIM record that is not discovered is shown as unconfirmed, rather than proof that signing is broken.

DNS PROPAGATION
Compare answers from 35+ public resolvers, view captured responses on a map, and track an expected value or resolver agreement. Resolver locations identify the resolver services; checks are not independent probes running in each city.

SAVED DOMAINS AND MONITORING
Keep your domains together and see which findings need attention. Create health or propagation monitors, receive push alerts, and inspect the evidence from previous checks. Saving a domain and enabling monitoring are separate actions.

FREE TO USE
Manual tools and explanations remain free. Guest accounts include 2 monitors; signing in includes 5 monitors, hourly checks and the latest 11 checks per monitor.

OPTIONAL DNS KIT PRO
Upgrade to up to 100 monitors, checks as often as every 5 minutes, and the latest 100 checks per monitor. Choose a monthly or annual auto-renewing subscription. Prices and billing periods are shown before purchase. Timing can vary during outages or heavy load. Saved history builds from future checks.

Subscriptions renew automatically unless cancelled in Google Play. When Pro expires, retained monitors return to hourly checks and newer monitors beyond the free allowance pause. Monitor definitions are not deleted.
