Answer :
Option (A,C,F) The valid IP addresses for hosts in the 10.1.160.0/20 subnet are 10.1.169.0, 10.1.175.254, and 10.1.160.255. These addresses fall within the subnet range of 10.1.160.0 to 10.1.175.255. Addresses like 10.1.176.1 fall outside this range and are not valid.
To determine the valid IP addresses for hosts in the given subnet, we need to calculate the range of addresses within the 10.1.160.0/20 subnet.
A /20 subnet mask means that the first 20 bits of the IP address are for the network part, and the remaining bits are for host addresses. This equates to 255.255.240.0 in dotted decimal notation.
The 10.1.160.0/20 subnet covers the IP address range from 10.1.160.0 to 10.1.175.255.
Let's validate the given IP addresses:
- 10.1.169.0 - This address falls within the range, so it is valid.
- 10.1.176.1 - This address is outside the range (10.1.160.0 - 10.1.175.255), so it is not valid.
- 10.1.175.254 - This address is within the range, so it is valid.
- 10.1.160.0 - This address is the network address, which typically isn't assigned to hosts, but technically it is within the range.
- 10.1.175.255 - This address is the broadcast address, which is not usually assigned to hosts, but is technically within the range.
- 10.1.160.255 - This address falls within the range and can be assigned to a host.
Therefore, the valid host IP addresses are 10.1.169.0, 10.1.175.254, and 10.1.160.255.
