parameters:

• Hostname — Specify a fully qualified domain name as the system hostname.

Note: If you change the hostname and you are using Offense Resolution, we
recommend you also update the Resolver Agent name, if a Resolver Agent is
assigned to the host.

• Gateway - Specify the default gateway of the system.

Public IP address is often configured using Network Address Translation (NAT)
services on your network or firewall settings on your network. NAT translates an
IP address in one network to a different IP address in another network.
