DNS Lookup
Validation Error
DNS Query Results for:
When a domain isn't behaving the way you expect, a wrong IP, email that never arrives, a subdomain that won't resolve, the DNS records are almost always where the answer's hiding. Most people end up hunting across three or four different sites to piece together the full picture, one for MX, another for TXT, another just to confirm the A record. It's slow, and it's easy to miss the one record that's actually causing the problem.
This tool pulls the full set in one go, A, AAAA, CNAME, MX, TXT, NS, SOA and SRV, so you can see everything at once instead of switching tabs five times. Handy for troubleshooting your own domain, checking one before you rely on it, or just confirming a DNS change actually went through.
Retrieve all standard DNS records including A, AAAA, CNAME, MX, TXT, NS, SOA, and SRV records instantly.
Verify your MX records and SPF (TXT) policies to ensure your email deliverability is functioning correctly.
Diagnose misconfigured canonical names, missing records, or outdated TTL caches to keep your website online.
Common things people check for
- Confirming an A record points to the correct server IP
- Verifying MX records for email routing
- Checking TXT records for SPF or domain verification codes
- Spotting a CNAME that's aliasing to the wrong target
Troubleshooting with DNS Lookup
A misconfigured record is one of the most common reasons a website goes down or email stops arriving after a migration. Running a full lookup and comparing it against what you expect to see is usually the fastest way to spot the mistake. If the record looks correct but the change still hasn't shown up everywhere, check DNS Propagation Check next, or force it along with Clear DNS Cache.
FAQS
What is a DNS Lookup?
A DNS Lookup queries the Domain Name System to retrieve the underlying records (like IP addresses) associated with a human-readable domain name.
What does an A Record do?
An A (Address) record maps a domain name to an IPv4 address, which is the most fundamental step in directing web traffic to a server.
How do I verify email setup?
You can verify your email setup by checking the MX (Mail Exchange) records to see which servers handle incoming mail, and TXT records for SPF/DKIM policies.
What is a CNAME?
A Canonical Name (CNAME) record maps one domain name to another, often used to alias subdomains like 'www' to the root domain.
