In the PROD lab environment, the hostname -A command returns both the FQDN and the short hostname, indicating that full hostname resolution is functioning. However, in the disconnected lab environment, the same command returns only the FQDN. This suggests that hostname resolution is limited or partially configured in the disconnected environment.

PROD Environment Output:

workstation.lab.example.com workstation

Disconnected Environment Output:

workstation.lab.example.com
