Part (b)
Consider a host with the following information:
IP Address. . . . . . . . : 131.183.116.98
Subnet Mask . . . . . . : 255.255.224.0
Default Gateway . . . : 131.183.127.252
1) What Class is this address?
This is a class B address.
2) How would this IP address be expressed using CIDR notation?
131.183.116.0/22
3) What portion of this IP address identifies the network?
0.0.001.255
4) What portion of this IP address identifies the host?
255.255.0.0
5) Has it been sub-netted? How do you know?
Yes it has, you can tell because the subnet mask isn’t 255.255.255.255
6) Does the “network” use a fixed length subnet mask (FSLM) or a variable length subnet mask! (VLSM)?
It is FSLM because the subnet mask is not a 255 or 0 in each separate octet.
