Subnetting Question

Guys, could you help me with a subnetting question? Sorry if it's basic, but I think I am thinking too much about it and getting confused.

If we have IP Address:

172.20.106.219/23

The network address is:

172.20.106.0

and the broadcast address is :

172.20.107.255

(Right so far, I hope)

My question is are the following IP addresses valid host addresses on this subnet?

172.20.106.255 and 172.20.107.0

I think the answer is yes, but confirmation would be most appreciated.

Many thanks!

Pete
