Add the Azure wire server (168.63.129.16), Oracle (192.0.0.192) and
Alibaba (100.100.100.200) addresses to the metadata list. The Azure one
is public, so web_fetch reached it. Check the IPv4 address inside a
64:ff9b::/96 address too, so private addresses and metadata addresses
cannot be reached through NAT64 when private addresses are allowed.
