Hi,

You can have 64 /26 in a /20 subnet.

xxxxxxxx xxxxxxxx xxxx|xxxx xxxxxxxx /20

xxxxxxxx xxxxxxxx xxxxxxxx xx|xxxxxx /26

Therefore you have 6 bits to address 64 subnet with /26 in a /20 subnet.

HTH,

Mohammed Mahmoud.

... And if you use only 2 out of those 64, you will have 2x /26 in a /20.
