I found a subnetting practice site and was doing 'ok' -- until this question:

What is the last valid host on the subnetwork 192.168.149.0 255.255.255.224?

224 means increments of 32, correct? So that would be 0, 32, 64, 96,,128, 160 so the last valid address would be 192.168.159.30, correct?

But the answer given is 192.168.149.30.

Maybe a typo and they meant 192.168.159.30?

Otherwise, can you please explain where I am going wrong on this one?
