DNS records
Look up a domain’s public DNS records.
Queries run from Zunavek's resolver.
What the records mean
- A and AAAA map a domain to IPv4 and IPv6 addresses.
- CNAME points one domain name to another as an alias.
- MX specifies receiving mail servers and their priority.
- TXT holds verification and policy data such as SPF, DKIM, and DMARC.
- NS lists authoritative nameservers.
- SOA describes the zone's authority and maintenance settings. Its minimum TTL is used for negative caching, not as each record's TTL.
What is forward DNS?
Forward DNS resolves domain names into IP addresses and other DNS records. Applications can reuse cached answers or ask a resolver when they need fresh information. This lookup shows the answers returned through Zunavek's resolver.
Common use cases
- Check this resolver's answers after DNS changes.
- Inspect MX and TXT records; enter the full selector hostname for DKIM or _dmarc hostname for DMARC.
- Inspect NS answers after nameserver changes or a domain transfer.
- Audit TXT records for configuration issues.
Frequently asked questions
What is the difference between forward and reverse DNS?
Forward DNS converts a domain name into an IP address (A/AAAA records). Reverse DNS converts an IP address back into a hostname using PTR records.
How long does DNS propagation take?
There is no universal 1-48 hour window. Cached answers can remain until their earlier TTL expires, and authoritative updates, delegation changes, and negative caching can affect what a resolver sees. Lowering a TTL does not erase answers already cached under the old value. This tool shows one resolver's view, not worldwide propagation. See RFC 1034 on caching and TTLs.
Why is my domain not resolving?
Common causes include incorrect nameserver delegation, expired domain registration, missing A/AAAA records, or cached older answers. Use this tool to inspect what this resolver currently returns for your domain.
