Function: isPrivateHost()

isPrivateHost(host): Promise<boolean>

Defined in: safe-fetch.ts:73

Decide whether host resolves to a private/loopback/link-local address. Host literals are checked exactly; hostnames are resolved via node:dns/promises when available. Fails closed on any DNS failure (e.g. edge runtime) so a misconfigured resolver can't open the SSRF gap.
