A systems administrator was tasked with assigning the temporary IP address/netmask 192.168.168.1/255.255.255.255 to the interface eth0 of a Linux server.

When adding the address, the following error appears:

# ip address add 192.168.168.1/33 dev eth0

Error: any valid prefix is expected rather than "192.168.168.1/33".

AThe CIDR value /33 should be /32 instead.

BThere is no route to 192.168.168.1/33.

The answer is definitely A. The CIDR value is invalid, and the admin should use /32 instead.

I bet the admin was trying to reserve a whole galaxy for that server. /33 is a bit overkill, don't you think?

User 1: Yeah, /33 is definitely too much for a single server.

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.

A: It's important to double-check the subnet mask before assigning it.

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.
