What
A hook is a command or web address that Claude Code calls at set moments. An HTTP hook calls a web address, and Claude Code blocks addresses that are private. When the hook's address is itself an IP address, the error now says that address is not a public address. When it is a name that leads to a private address, the error still says the name resolves to a private or link-local address. Loopback addresses (127.0.0.1 and ::1) are still allowed for local development.
Why
The message reads more clearly when a hook URL is written as a plain IP address.
