Performs an A record DNS query, using System.Net.Sockets.Socket and building a UDP packet.
Why?:
In PowerShell 2 there was no way to direct your DNS query to a custom server. In PowerShell 3 and higher this was resolved when Resolve-DNSName was introduced.
NOTE:
This currently only sends the packet to the DNS server and does not retrieve a result. Will add in the support for retriving the result later.
