DNS Records Checker& Viewer
Inspect DNS records in real time — including TTL, DNSSEC, and common configuration errors. Built for developers, marketers, and SEO specialists.
What This DNS Checker Does
We resolve a domain against authoritative nameservers and present all key records (A, AAAA, CNAME, MX, NS, TXT, SRV, CAA, PTR, SOA). For each record we show value, TTL, and additional context such as preference/priority, flags, and signature status.
🔍 How It Works
✅ Key Features
- • Overview of all common record types
- • DNSSEC validation
- • CAA verification
- • SOA serial/refresh checking
- • Multiple resolvers (authority/recursion)
- • JSON/CSV export
💡 Instant DNS Record Checks
Run instant DNS record checks for any domain. This tool queries authoritative sources, surfaces TTLs and DNSSEC details, and flags common misconfigurations that affect delivery, security, and SEO.

Frequently Asked Questions
Do you query authoritative nameservers?
Yes. We prefer authoritative data and may compare recursive resolvers for propagation insights.
Do you support SPF/DKIM/DMARC?
We parse TXT records, highlight SPF limits, and report DKIM/DMARC presence with alignment hints.
Will you show TTLs?
Yes, TTL is displayed for each record to explain cache behavior and propagation timings.
Do you check DNSSEC?
We validate the DNSSEC chain (DS, DNSKEY, RRSIG) where available and report issues.
Can I export results?
Yes. Copy, CSV/JSON export, and a REST API are available for automation.
Should I expect global propagation times?
Propagation varies with TTL and caches. We provide regional samples to illustrate variance.
