Is a .mil name registered?
Looked up from your browser in the registry's RDAP service; if that does not answer, in DNS. Nothing is stored on dnssec.in.What this means
The root zone holds a DS record for .mil, so the extension is signed and anchored. A domain under .mil can use DNSSEC with a full chain of trust: it needs to be signed at its DNS host and have its own DS at the registrar.
IDN names under .mil
No IDN tables for .mil at IANA: names are usually ASCII only (a–z, 0–9 and hyphen).
Length
DNS limits are the same everywhere: each label is 1 to 63 characters, the whole name at most 253, letters, digits and hyphens, not starting or ending with a hyphen. IDN labels count their xn-- form, so fewer native characters fit. A registry can set a higher minimum (often 2 or 3 characters) or reserve short names: that is in its own policy.
WHOIS and RDAP
This extension is not in IANA's RDAP list. There is no classic WHOIS server (port 43): since January 2025 ICANN lets gTLD registries offer RDAP only. For most gTLD names the owner's contact details are redacted for privacy; the registrar, dates and status are public.
Lifecycle and drop
A restricted extension: who may register, and what happens at expiry, is set by its registry under its own rules, not by the usual ICANN registrar process.
