hi, am doing a case study of ccna sem3, and will doing it i got this messege:

ADMIN(config-if)#ip address 223.0.0.64 255.255.255.240
Bad mask /28 for address 223.0.0.64

Its because of VLSM but does version 4.0 support it?

the IP 223.0.0.64 has all zeros in the host bits when you use a mask of /28. You con not assign such an IP to an interface. Try this IP: 223.0.0.65

or change the subnet mask to 255.255.255.128
