Is this the same as nslookup on my computer?

The layout is similar, but the query goes to public DoH. Interactive mode and set type=ANY are not reproduced.

What is the Server line?

The identifier of the DNS-over-HTTPS source that was used.

What if the result is empty?

Either the name is missing (NXDOMAIN) or that type is absent (NODATA). See the resolve row.

Where is the query sent?

Public DNS over HTTPS. The host name is the question.

Is personal data sent?

Only the host name you enter. No account or contact data is used.

How do I find a hostname from an IP?

Select PTR and enter a public IPv4 or IPv6 address. We construct its reverse name and query public DNS. Private IPs are excluded. Missing PTR records do not necessarily indicate a web connection problem.

nslookup

Inspect name resolution the way nslookup presents it.

What this tool does

Public DNS answers arranged like nslookup Server / Name / Address. There is no interactive mode and no arbitrary server pin.

How to read the result

Server is the DoH source that answered. Name is the host that was asked. Address lists A / AAAA; other types follow with their type label.

Glossary

nslookup: A classic presentation of name resolution as Server / Name / Address.
A: An IPv4 address record.
AAAA: An IPv6 address record.
TTL: How long that answer may be reused. This layout may omit the number on a line.

Check from your own device

Use dig on macOS or Linux, or nslookup on Windows. Each command queries one record type. Your device uses its own DNS settings and cache, so its results may differ from this page.

dig xn--bcher-kva.de A

nslookup -type=A xn--bcher-kva.de

When expected records are missing

Check the exact name and type. A www host and the zone apex are different names; reverse DNS uses PTR.
Check the delegated name servers with NS, then inspect records in the corresponding control panel. The SOA serial helps compare zone revisions.
After a change, caches may retain data for the previous TTL. TTL does not guarantee a worldwide completion time.
SERVFAIL and transport failures do not mean a record is absent. Investigate delegation, DNSSEC and resolver availability.

Response details and sources

Details come from DNS-over-HTTPS JSON responses. Omitted sections and flags are marked as not reported. AD reports the resolver's DNSSEC validation; these are not direct connections from your browser to an authoritative DNS server.
