in thread assigning hash key to reference of array question

It's actually very simple to map out data structures. If it's tricky, something has gone wrong.

A collection of servers is a hash of servers keyed by name.
A server is a collection of IP addresses.
A collection of IP addresses is an array of IP addresses in dotted form.

It looks to me like you are unintentionally creating “a reference to a reference.”

His structure is fine. The problem is that he was replacing the collection of IP addresses when he wanted to add to it.
