Today during a free online CCENT exam I was given the following question:
Which 2 statements best describe IP Address 10.16.3.65/23?
The 2 answers were:
The Broadcast Address of the subnet is 10.16.3.255
The Lowest Host Address in the subnet is 10.16.2.1/23
My questions are, how is this question solved methodically and whats happening to the 3rd octet? It seems to be changing from .3 to .2 when there is only 1 bit in the 3rd octet to play with (NNNNNNNH).
