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
- 1Enter a domain name (e.g., example.com)
- 2Query authoritative nameservers for all record types
- 3Display results with TTL, diagnostics, and warnings
Key Features
- All common record types overview
- DNSSEC validation
- CAA verification
- SOA serial/refresh checking
- Multiple resolvers (authority/recursion)
- JSON/CSV export
Core Records
- A & AAAA: IPv4 and IPv6 addresses with TTLs
- CNAME: Canonical name mapping with chain detection
- MX: Mail exchangers with priority and target validation
- NS: Delegation targets with consistency tests
Advanced Records
- TXT: SPF, DKIM, DMARC parsing and diagnostics
- SRV: Service location with priority and weight
- CAA: Certificate Authority Authorization
- SOA: Zone parameters and serial numbers
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.
