Warning: Advanced Topic! This topic is related to developing Vagrant plugins. If you are not interested in this or you are just starting with Vagrant, it is safe to skip this page.
If you are developing a custom Vagrant provider, you will need to do a tiny bit more work in order for it to work well with Vagrant Share.
For now, this is only one step:
public_address provider capability - You must implement this capability to return a string that is an address that can be used to access the guest from Vagrant. This does not need to be a globally routable address, it only needs to be accessible from the machine running Vagrant. If you cannot detect an address, return nil.
