getaddrinfo() supports the address%scope-id notation for specifying the IPv6 scope-ID.

CFEngine does not seem to know about that and try to parse it as an IPv6 address directly.

It seems that that bug will become quite common, and it's a pity we don't support ipv6 well. Moreover, it's not clear how you can workaround that if your infra is ipv6 only. Is there any?
