Outbound requests to cloud metadata hostnames and private, link-local or loopback ranges are now blocked.
New IP and hostname classification logic recognizes cloud metadata hostnames, including metadata.google.internal and instance-data endpoints, along with private, link-local, loopback, NAT64, and 6to4 IPv4-mapped IPv6 ranges, as unsafe destinations. This is used to block outbound requests to cloud metadata services and internal addresses.
