An internal IP in a public document is not routable and still names the subnet,
and the example does not need a literal — the check is that a hostname with no
listener returns 404, and any node address demonstrates it.
Caught by grepping the fresh public history for anything version- or
address-shaped, which is a thing worth doing once per repository that changes
visibility.
