Because of the IP Address configuration, it needs to be indented from the 10.0.0.32/27 network (host 10.0.0.33 to 10.0.0.62 - Broadcast 10.0.0.63). Prefix 27 minus 32 = 5 left over used for host (1=2 - 2=4 - 3=8 - 4=16 - 5=32), i.e. we have a range of 32 hosts available in each subnet: Subnet 10.0.0.0 - 10.0.0.32 - 10.0.0.64 - 10.0.0.96 - 10.0.0.128 - 10.0.0.160 - 10.0.0.192 - 10.0.0.224.

How did you get 10.0.0.34? I can if the answer is 10.0.0.33 but not 34. Thank you for your time in advance.
