# Whisper NIC: reserved and premium names, in full.

> Published straight from the files the registration path enforces, so what you
> read is exactly what is blocked.

A registry that blocks names should say which ones, and prove it. Every list below
is served straight from the file the registration path itself checks. What you read
here is exactly what is rejected when you register; there is no second copy to drift
out of step. Three classes of name are held back, each with its own clear, distinct
reason at registration. Everything else is yours to take.

Read the rules these lists serve on the naming policy:

## Reserved infrastructure names (blocked)

**199** labels are reserved so a friendly-name cannot
impersonate the infrastructure or mislead a reader: the RFC 2142 role mailbox names
(`hostmaster`, `postmaster`, `abuse`, `security`, and the rest), common
infrastructure hostnames, and our own Whisper service names (`ns1` through `ns99`,
`doh`, `rdap`, `whois`, `nic`, and so on). Asking for one is refused with a clear
"reserved name" reason. We author this list ourselves, so it carries no external
licence. Matched whole-label and case-insensitively (Scunthorpe-safe).

## Premium names (held)

**181** labels are a hand-picked set of high-value generic terms
(such as `bank`, `login`, `wallet`) and well-known brand names, held as premium to
prevent squatting and impersonation. Ordinary common words are not on this list and
stay freely registrable; only this curated subset is held. Asking for one is refused
with a distinct "premium name, contact us" reason, and it is held for a future
acquisition process. We author this curated list ourselves; it carries no external
licence. Want one for a genuine, stated use? Write to <registry@whisper.security>.

## Offensive names (blocked)

Names matching our offensive-content blocklist are rejected with a clear reason.
**279** single-label tokens are enforced (multi-word phrases in
the upstream file cannot match a single DNS label, so they are kept for reference but
never block a label). We do not print the slurs inline; the list is offered as a
labelled download for anyone who needs to audit exactly what is blocked.

- Download (verbatim, the enforced file): <https://nic.whisper.online/lists/offensive.txt>

## Common words (reference, not blocked)

We keep a comprehensive English word list as the registry's vocabulary reference and
as the basis for curating the premium set, but it is **not** enforced and **not**
republished here: ordinary common words are yours to register. The reference is
dwyl/english-words (`words_alpha.txt`), in the public domain under the Unlicense.
