+ Some operating systems will prefer IPv6 to IPv4 addresses even if the
+ system has no IPv6 connectivity which is usually not expected by the user.
+ Some even rely on DNS to resolve localhost which mean the "localhost" address
+ used may not actually be local.

+ It is therefore recommended to explicitly configure the intended IP address
+ instead of relying on the operating system, unless there's a strong reason not to.
