DNS Propagation Checker
Query A/AAAA/CNAME/TXT/MX/NS records. Recursive vs Authoritative views help catch stale caches or misconfigurations.
Recursive results
Authoritative results
How it works
The tool asks your server to resolve the domain and returns answers as seen by a recursive resolver. Authoritative view queries the domain’s NS to bypass caches (enable /api/network/dns-check-authority).
Tips: after DNS changes, start with NS answers to confirm the zone, then compare with recursive results. Check TTLs and consider CDN propagation delays.
O narzędziu
Use this DNS checker to confirm which records are visible on the internet. It’s helpful after DNS changes (new A record, MX setup, SPF/DKIM updates) when you want to verify that resolvers return the expected values.
DNS propagation is not always instant. Some resolvers cache results based on TTL, and authoritative misconfigurations can cause inconsistent responses. This tool makes it easier to compare what different lookups return so you can identify where the mismatch happens.
For email deliverability, DNS is especially critical: MX, SPF, DKIM and DMARC must be correct. If your site is not reachable, A/AAAA and CNAME records are often the first place to check.
