A network address can never end in an odd number.  Given the IP address
172.16.0.1 and a /21 subnet mask, the network number in this case would be
172.16.0.0.  The next network number would be 172.16.8.0 and so forth.

Hi Group members,

I came across a question in a Transcender exam in which they give a network 
address as 172.16.0.1/21. This address is given by an ISP to your network. 
Is that address a possible network address? It looks to me as a host 
address. What I'm missing here?

Regards to all

Adia
