.app WHOIS Lookup: Records in an Application Extension
.app is a generic extension delegated to the root zone on 25 June 2015 and operated by Charleston Road Registry Inc. Its IANA entry lists no WHOIS server, so a classic query on port 43 gets no answer. Registration data is published only through the registry's RDAP service at pubapi.registry.google, which returns each record as structured JSON. DNSSEC signs the .app zone.
The RDAP record of a .app domain contains the registration, expiry and last-change dates, the sponsoring registrar, status codes, name servers and DNSSEC details. The registrar is the only contact it lists; the holder's name, address and email are left out of the reply. The registry's other extension is covered on the .dev WHOIS lookup page, and the .info WHOIS lookup shows another generic extension without a port 43 service.

WHOIS FAQ
Why does a whois command return nothing for a .app domain?
A command-line whois client returns nothing for .app because the extension has no port 43 server to ask. Since 28 January 2025, RDAP has been the authoritative source of registration data for generic extensions, and registries are no longer required to provide WHOIS. To read a .app record outside this site, you need a client that speaks RDAP.
Can I find out who owns a .app domain?
No, the RDAP record of a .app domain does not reveal its owner, because the registry keeps the holder's identity out of the reply. The only contact in the record is the registrar through which the name was registered. For a purchase offer or a legal notice, send your request to that registrar, whose name appears in the result.
When does a .app domain expire, and where can I see it?
The expiry date of a .app domain sits in its RDAP record as an expiration event, next to the registration and last-change events. whois.com.tr turns these events into ordinary dates and also shows the domain's age and the days left until expiry. With only a few weeks to go, it is time for the holder to renew.
Why are status codes spelled with spaces in a .app record?
RDAP writes EPP status codes as separate lowercase words, so a lock that WHOIS shows as clientTransferProhibited appears as client transfer prohibited in a .app reply. Both spellings mean the same thing. Codes starting with client are set by the registrar and can be lifted by it; codes starting with server are set by the registry.
Is my .app domain signed with DNSSEC because the zone is?
No, a signed .app zone does not mean every .app domain is signed. The zone signature covers the extension itself; a single name counts as signed only once a DS record has been published for it. The secure DNS section of the RDAP record reports this name by name, and the result screen shows it separately from the zone status.
How can I tell if a .app name is available?
An unregistered .app name has no RDAP record, so the registry's service replies that the domain was not found and returns no fields at all. whois.com.tr reads that reply as an available name. You can then register it with any registrar that offers .app, provided nobody else gets there first.
