DNS Checker
Look up a domain's A, AAAA, MX, TXT, NS and CNAME records right now.
What this tool does
Looks up a domain's current A, AAAA, CNAME, MX, NS and TXT records directly from DNS.
How to use it
Enter a domain name (without http:// or a path). The checker queries each record type independently and lists whatever is found — a domain with no MX records, for instance, simply shows an empty mail section rather than an error.
Example
Looking up a domain with a single web server and a third-party email provider shows its A record's IP address alongside separate MX records pointing to the mail provider's servers.
Validation and safety
The input must be a syntactically valid domain name. Each of the six record types is queried independently, so a failure or absence in one (such as no AAAA record for an IPv4-only site) does not prevent the others from showing results.
How to interpret the result
Results reflect what this server's DNS resolver sees right now — DNS propagation means a different resolver or location can briefly see different values after a recent change, and TTL caching means a very recent change may not appear immediately everywhere.
Limitations
This is a direct DNS snapshot, not a full DNS health check — it does not verify SPF/DKIM/DMARC record correctness beyond showing the raw TXT records, does not check nameserver authority delegation, and does not query less common record types such as SRV or CAA.
Privacy
This tool sends the address you enter to Quiklio's own server, which makes the network request on your behalf — the target address is not sent to any third party beyond what a normal request to that address would reveal.
Frequently Asked Questions
- What does DNS Checker do?
- Looks up a domain's current A, AAAA, CNAME, MX, NS and TXT records directly from DNS.
- Can this be used to probe internal or private addresses?
- This tool only performs a DNS lookup — it does not connect to the addresses those records point to, so there is no private-network address to block. Lookups are rate-limited per visitor to prevent abuse, and only standard public DNS records are returned.
- Is the checked address shared with anyone else?
- This tool sends the address you enter to Quiklio's own server, which makes the network request on your behalf — the target address is not sent to any third party beyond what a normal request to that address would reveal.
