Query A, MX, NS, TXT and other types via the resolver you pick.
DNS turns a name into IPs, mail hosts and text. Different resolvers (Google, Cloudflare, Quad9) may differ briefly because of cache.
ALL fetches common types in parallel. Pick one type to narrow the query. Answers are what this server got from the chosen resolver, not your home DNS.
You can also open iptool.tr/example.com for a full intoDNS-style report of every record.
A is IPv4, AAAA IPv6, MX mail hosts, NS the authoritative nameservers, SOA the zone identity, TXT SPF and verification strings. CAA limits which CAs may issue. DS and DNSKEY belong to the DNSSEC chain.
The resolver you pick changes the cache: Cloudflare 1.1.1.1, Google 8.8.8.8 and Quad9 9.9.9.9 can show different leftover TTLs. The full report gathers parent NS, glue, www A/AAAA and IPv6 in intoDNS-style findings.
Frequently asked questions
What does ALL do?
It asks A, AAAA, MX, NS, TXT, SOA, CAA and other common types at once.
No records — is the site down?
No A/AAAA means the web name does not resolve. No MX means no inbound mail. No NS means the zone is not published.
Which resolver should I use?
Cloudflare and Google are fast and common. Quad9 may filter malicious names. Compare the same domain on two resolvers.
What does TTL mean?
Time to live is how many seconds a resolver may cache the record. Low TTL spreads changes faster; high TTL cuts query load.
www vs apex?
Apex (example.com) and www are different names. One may be CNAME, the other A. The full report checks both.
Is missing IPv6 a problem?
The site can still load on IPv4. Missing AAAA is often a warning, not an error. Add AAAA if you want dual-stack.
Why do NS records matter?
NS says which servers publish the zone. Wrong NS or glue takes the name down entirely.
Why does this differ from my nslookup?
Queries leave from the iptool.tr host to a public resolver. Your ISP DNS keeps a separate cache.
