Lab 6.7.4 IPv4 Address Subnetting, Part 2
Let’s add some of this information to our table:
Host IP address|172.25.114.250|
Major network mask|255.255.0.0 (/16)|
Major (base) network address|172.25.255.255|
Total Number of Host BitsNumber of hosts|16 bits or 216 or 65,536 total hosts| Subnet mask|255.255.255.192 (/26)|
Number of subnet bitsNumber of subnets|261024 (210)|
Number of host bits per subnetNumber of usable hosts per subnet|664 – 2 = 62 (from 26 – 2)| IP for first host on this subnet|172.25.114.192|
IP address of the last host on this subnet|172.25.114.254|
Broadcast address for this subnet|172.25.114.255|
