Lab 6.7.4 IPv4 Address Subnetting, Part 2
Let’s add some of this information to our table:
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|

Create a subnetting worksheet to show and record all work for each problem. Problem 1:
Number of subnet bits|8|
Number of subnets|256 – 2 = 254|
Number of host bits per subnet|8|
Number of usable hosts per subnet|256 – 2 = 254|
IP address of first host on this subnet|172.30.1.1|
IP address of last host on this subnet|172.30.1.254|

Problem 2:
Number of subnet bits|14|
Number of subnets|16,384 – 2 = 16,382|
Number of host bits per subnet|4 – 2 = 2|
Number of usable hosts per subnet|2|
IP address of first host on this subnet|172.30.1.33|
IP address of last host on this subnet|172.30.1.34|

Problem 3:
Number of subnet bits|24|
Number of subnets|16 777 216 (224)|
Number of host bits per subnet|8|
Number of usable hosts per subnet|256 – 2 = 254|
IP address of first host on this subnet|192.192.10.1|
IP address of last host on this subnet|192.192.10.254|
