Module host_pattern 

Matching for persisted network host entries.

Bare entries retain the original exact-or-subdomain behavior. New strict entries use =host for exact matching or *.host for subdomains only. The = prefix is internal; users write --allow-host-pattern host. Host syntax follows RFC 1035 §§2.3.1, 2.3.4, 3.1 and RFC 1123 §2.1.

Functions

encode_strict

Encode an opt-in host pattern for storage alongside legacy entries.

matches

Match a hostname against a legacy or opt-in network entry.

static_resolution_host

Get the exact hostname to resolve into static CIDRs, if one exists. Wildcard entries learn their addresses as concrete DNS queries succeed.
