What is the subnetwork number of a host with an IP address of 172.16.66.0/21?
Hi,
First of all this is not a valid IP address to assign a host. According to the subnet mask , the block size is 8. So this address space is lies between the 172.16.64.0(network address) to 172.16.71.255(broadcast address). The usable host IP range 172.16.64.1 - 172.16.71.254 .
Hope it helps.
Thanks.
