DNS Lookup.
How does DNS Lookup work?
Enter a domain name, pick a record type (or ALL) and click “Check”. Our servers query DNS and show the records they find, with TTL where DNS provides it, so you can confirm your configuration or troubleshoot a problem.
What are DNS records?
DNS records are entries in your domain's zone that tell the internet where to send traffic: they map names to IP addresses, point subdomains to other hosts, route e-mail and prove domain ownership. Read the full guide.
Which DNS record should you check?
- A: Points a name to an IPv4 address (most websites)
- AAAA: Points a name to an IPv6 address
- CNAME: Makes one name an alias of another
- MX: Routes the domain's e-mail to its mail servers, by priority
- TXT: Free text: verification and e-mail security (SPF, DKIM, DMARC)
- CAA: Limits which certificate authorities may issue certificates
- NS: The nameservers responsible for the domain
- SOA: Zone details: primary nameserver, serial number and timers
- SPF: Which servers may send e-mail for the domain
- DKIM: Public keys that let receivers verify signed e-mail
- DMARC: What receivers should do when SPF/DKIM fail, and where to report
- PTR: Reverse DNS: maps an IP address back to a name
- SRV: Service locations, such as SIP or XMPP servers and ports
