Because 202.176.56.* has 256 hosts and 202.176.57.* has another 256.

I'm a bit confused about the ranges. I thought it was just 64 hosts since we're only using two octets.

I practiced something similar, and I think it was about calculating the total hosts in a range. Could it be 1024?

If we're scanning 202.176.56-57.*, that means we're looking at two full subnets, right? So maybe it's 512 hosts?

I think I remember that the last octet can have 256 values, but I'm not sure how the range affects that.
