More Subnetting

[Erik]

In studying for my CCNA I cam across the following question about subnetting in the practice tests provided with the Cisco books:

How many hosts are on the following subnet? What are those hosts?

192.168.5.64 255.255.255.227

Wait, you can't use 255.255.255.227 as a subnet! According to the test the right answer is that it creates 30 hosts, 192.168.5.65 - 192.168.5.94, which would be correct for a mask of 255.255.255.224. So am I right in guessing that this is just a misprint in the question?

TIA

BTW, hoping to sit for the test in the first half of August. Then on to A+.

spot on - you can't use 227 as a subnet mask, the number has to be either
128
192
224
240
248
252

Anything else won't work (in any octet that is)

Best of luck with the exam. I took the first half last year and am expecting to do the ICND in a couple of weeks (would have done it last week, but I had an argument with a car which left me with whiplash instead :eek: )
