here is the question
Your router has the following IP address on Ethernet0: \(\displaystyle 172.16.2.1/23\). Which of the following can be valid host IDs on the LAN interface attached to the router? (Choose two.)
A. \(\displaystyle 172.16.0.5\)
B. \(\displaystyle 172.16.1.100\)
C. \(\displaystyle 172.16.1.198\)
D. \(\displaystyle 172.16.2.255\)
E. \(\displaystyle 172.16.3.0\)
F. \(\displaystyle 172.16.3.255\)
my attemb
i know this IP \(\displaystyle 172.16.2.1\) belong to class \(\displaystyle B\) and the range of IP addresses in class \(\displaystyle B\) is from \(\displaystyle 128.0.0.0\) to \(\displaystyle 191.255.255.255\)
so all option given is within the range
i'm confused
why some IPs is valid and some is invalid
