ping responds to factory ip

When running checkip for Exadata x8M-2, I am getting below

 Processing section FACTORY

ERROR : 192.168.1.1 is responding to ping request

GOOD : 192.168.1.10 is not responding to ping request

GOOD : 192.168.1.101 is not responding to ping request

GOOD : 192.168.1.102 is not responding to ping request

GOOD : 192.168.1.103 is not responding to ping request

GOOD : 192.168.1.104 is not responding to ping request

Based on below oracle document I can safely ignore the error.

OEDA - Error encountered while running checkip (Doc ID 2227862.1)

When I start re-imaging will be starting with all cables plugged in to the core network and management network, is that alright?

Thank you and kind regards
