Hmm, I guess the admin was trying to assign a subnet mask with more than 32 bits. Looks like they need to refresh their networking knowledge.

The CIDR value /33 is the issue here. A /33 prefix is not valid as the maximum prefix length is /32.

I'm not sure, but maybe the IP address 192.168.168.1 is already in use causing the error.

I agree with Esteban, the CIDR value should be /32 for the IP address to be valid.

I think the cause of the issue is that the CIDR value /33 should be /32 instead.
