ResolveError

Error returned by resolve_and_validate when a hostname cannot be safely resolved.

Functions

is_loopback_host

Returns true if host is a loopback target: an IP literal in the loopback range (127.0.0.0/8, ::1) or the well-known hostname localhost (case-insensitive).

is_private_ip

Returns true if addr is a non-routable or private IP address that should be blocked for outbound connections (SSRF defense).

resolve_and_validate

Resolves host:port via DNS and rejects the result if any resolved address is private, loopback, link-local, or otherwise non-routable per is_private_ip.
