DNS Lookup
Enter a domain name to query its current DNS records and inspect the values returned by public resolvers.
Results will appear here after the check runs.
DNS answers are point-in-time resolver observations and may differ while cached records propagate.
How to Use DNS Lookup
- Enter a bare domain such as example.com without a path.
- Run the lookup to retrieve the DNS data currently visible to the server.
- Match record types and values against your DNS provider, allowing for TTL-based propagation after a change.
How to Read DNS Lookup Results
DNS connects hostnames with services through record types such as A and AAAA addresses, MX mail routes, NS authoritative nameservers, TXT verification data, and CNAME aliases. The exact record set depends on the endpoint and what the queried domain publishes.
A returned value confirms what the resolver observed at that moment, not what every resolver worldwide has cached. Recently changed records can coexist until older cache entries expire. An absent record may also be intentional or restricted by the queried name and type.
DNS Lookup Example
A lookup for example.com may return an A record such as 192.0.2.10 and an MX record such as mail.example.com. The address is illustrative; real results come from the live query.
Frequently Asked Questions About DNS Lookup
Why does the lookup show an old DNS value?
Recursive resolvers cache records for their time to live. Until the previous TTL expires, different networks can return different values.
What is the difference between A and AAAA records?
An A record maps a name to an IPv4 address. An AAAA record maps it to an IPv6 address.
Why might a CNAME not appear at the root domain?
Traditional DNS rules do not allow a CNAME to coexist with other required apex records. Some providers offer ALIAS or flattening features instead.
