Bad Mask in Cisco Packet Tracer

Alhaji265

In Cisco Packet tracer, I am told to set a ip address of an interface (Fastethernet 0/0) to be the first address of network 10.0.0./30. I entered the following commands:

• interace Fastethernet 0/0
• ip address 10.0.0.0 255.255.252
• Bad mask /30 for address 10.0.0.0

It is stating that /30 is the bad mask, why is that? Thanks!

you cant assign 10.0.0.0 to the interface, it's the network address

10.0.0.1/30 will be ok
