$DNS_SERVERS Refactoring

[gabriel-vanca]

• Transform the list into a static property of the DNS_Server class
• transform the list of strings into a hashtable of objects clearly defined and with specific properties (IPv4, encryption, cyber risk etc)
• Move class into separate file

        static $DNS_SERVERS = ([System.Collections.Hashtable]([ordered]@{
            Google = [ordered]@{
                IPv4 = [ordered]@{
