[System.Net.Dns]::GetHostName() and [System.Net.DNS]::GetHostByName('') report different hostnames on same machine.

Query

Why does [System.Net.Dns]::GetHostName() report that my hostname is RQN6C6 but [System.Net.DNS]::GetHostByName('') report RQN6C6.Home?

Examples

PS /home/rokejulianlockhart> [System.Net.Dns]::GetHostName()
RQN6C6

PS /home/rokejulianlockhart> [System.Net.DNS]::GetHostByName('').HostName
RQN6C6.Home

PS /home/rokejulianlockhart> hostnamectl status
 Static hostname: RQN6C6
