Given that the very last bit from a binary perspective, it cannot be a
network address, unless you wanna split hairs and call /32s networks.
Note that is a reserved for private lan ip, 172.16.0.0-172.31.0.0 is the
reserved block this is part of, that particular /21 would be
172.16.0.0 to 172.16.7.
172.16.0.1 is a private IP range and is not routable on the Internet. So an
ISP would not give you this range. See RFC's 1918 and RFC 1597.

ack, before you nitpickers slam me, that entire private range block
ends in 172.31.255.255, not 172.31.0.0 as I stated previously.

OK first of all 172.16.0.0/21 is actually 172.16.0.0 255.255.248.0
Which means the network address are:
172.16.8.0
172.16.16.0
172.16.24.0
172.16.32.0
172.16.40.0 etc. etc. going up by 8 in the 3rd octet until you hit
172.16.248.0
So the answer is no because 172.16.0.1 falls into the first invali
Unless you use "ip subnet-zero" Then it starts with 172.16.0.0. ;^)
I agree though, either way you slice this, it's not a network address.

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.
