Subnetting a Class B Network that would allow for at least 510 hosts per subnet.
Write out my Binary…
512 256 128 64 32 16 8 4 2 1
I use the 256. 2^8 so I borrow 8 host bits = 256 minus 2.
New mask is… 255.255.254.0 or a /23
I believe I am 100% up to here… Now I wanted to see what IP address I can use… 172.16.X.X
Please refresh my memory, thanks.
