Internal IPv6 addresses are used when ExternalAddress is specified.

Line 314 in 683663e

if address.Type == v1.NodeExternalIP || (address.Type == v1.NodeInternalIP && suitableType(address.Address) == endpoint.RecordTypeAAAA) {

)

This commit introduced a change which checks if the ipv6 address is internal and uses it regardless of if we only want external ips. This seems very wrong.

I patched this out on my build and use a custom image.
