I came across a problem where an unroutable IP range was added to the IP Address manager. By default it appears that the range will be automatically set with status, "Available". But the addresses were being used and since the range was unroutable,it remained with status "Available", even after trying to scan. This is very misleading and could cause an issue if someone thought that an IP was available but is not.
Is there a way to change the default status so that it will only change once a scan is successful?
You can disable scanning of those IP Addresses, or the entire Subnet.
