Function host_is_local

pub fn host_is_local(host: &str) -> bool
Expand description

Whether a host string denotes this machine.

Literal addresses are parsed rather than string-matched, because ::ffff:127.0.0.1 is loopback wearing a different hat — the same bypass tools::fetch_guard::is_blocked_address documents on the SSRF side.

localhost is accepted by name. It is the one name a resolver is required to map to loopback, and refusing it would reject the most common local configuration for no gain.

Any other name is refused without resolving it. Resolution is a network call whose answer can change between the check and the connection, so a name that resolves to loopback today is not a guarantee — and a guard that makes a DNS request to decide whether to avoid the network has already lost.
