DNS Records Checker for your domain
DNS records checked online automatically
What does the DNS records checker cover?
How the DNS records check works
4 steps to a complete DNS audit
-
1 Step 1
Enter the domain
Submit your domain – no login required and no access to the DNS server.
-
2 Step 2
Run the DNS query
We query every relevant record (A, AAAA, MX, TXT, NS, CNAME, SOA) at the authoritative nameservers.
-
3 Step 3
Evaluate the records
You see each entry at a glance and get notes on missing SPF/DMARC and IPv6 configuration.
-
4 Step 4
Optimise the DNS
Fix missing or broken records at your DNS provider and improve email deliverability.
DNS record types explained
The most important record types at a glance – concise, precise, clear
- A / AAAA
- Maps a domain to an IPv4 (A) or IPv6 address (AAAA). Mandatory records for every reachable website.
- MX
- Defines the mail server(s) accepting mail for the domain. Multiple entries with priority values are possible.
- TXT
- Free-form text record used for domain verification (Google, Microsoft) and email authentication, among others.
- SPF
- TXT record specifying which mail servers may send mail on behalf of the domain. Defends against email spoofing.
- DKIM
- Cryptographic signature authenticating outgoing mail. The recipient verifies it against the DNS record.
- DMARC
- Policy for SPF/DKIM failures: defines what happens when a message fails authentication (none, quarantine, reject).
- NS / SOA
- NS lists the domain's authoritative nameservers. SOA holds management metadata like refresh interval and serial number.
- CNAME
- Alias record pointing one hostname to another. Often used for subdomains like www, blog or shop.
- CAA
- Specifies which certificate authorities may issue SSL certificates for the domain. Protects against mis-issuance.
- PTR
- Reverse DNS: maps an IP address back to a hostname. Important for mail-server reputation.
Common DNS errors
These configuration problems show up regularly on production domains
-
Multiple SPF records
Only a single SPF TXT record per domain is allowed. Multiple entries cause permanent fail authentication – mail lands in spam or is rejected outright.
-
DMARC with p=none and no reporting
A DMARC policy of p=none without a rua address is dead code: no protection, no visibility. Always set rua= to receive reports at minimum.
-
Missing CAA record
Without a CAA record any certificate authority can issue SSL certificates for your domain. That is a silent attack vector.
-
TTL below 60 seconds
Very low TTLs create unnecessary DNS load and slow down resolver answers. Outside active migrations, 3600s or higher is the norm.
-
No IPv6 (AAAA)
Without an AAAA record you lose IPv6 reachability. Mobile networks and big providers have been dual-stack for years – missing IPv6 costs performance and reach.
-
CNAME at the apex domain
CNAMEs on the root domain (e.g. example.com itself) are not allowed by spec. Use ALIAS or ANAME at your DNS provider instead.
Spot DNS issues with the DNS records checker
With the InspectWP DNS records checker you see every DNS entry of your domain in seconds. We audit A, AAAA, MX, TXT, NS and CNAME records and surface configuration errors that cause mail delivery problems, wrong IP resolution or broken subdomains. Find DNS issues before your visitors and mail servers stumble over them.
DNS records check – fast, online, no console required
Our crawler queries every relevant DNS record of your domain directly at the authoritative nameservers and audits the configuration. We detect missing SPF/DMARC entries, inconsistent nameserver answers, broken IPv6 configuration and CNAME resolution problems. The result is a complete DNS snapshot of your domain – without fighting dig or nslookup.
