Function: resolveHostIps()

resolveHostIps(input): Promise<string[]>

Resolve the host of input to its IP address(es) via the OS resolver (dns.lookup with all: true, so both A and AAAA records are returned when the host is dual-stacked). Accepts any net.UrlLike - a bare hostname, a full URL, or a { url } wrapper - and returns the deduplicated list of literal addresses. Never throws: an unparseable input, an IP-literal host (returned as-is without a DNS round-trip), or a resolution failure all yield the appropriate list or [].

dns.lookup (not resolve4 / resolve6) is used so /etc/hosts and the platform resolver order are honored, matching what an outbound connection to the host would actually use.
