172.29.0.0/16 subnetted to 113 subnets and provide information for subnets #1, #10, #26, and #113.

I need to have 113 subnets. I have to borrow host bits and convert them to subnet bits.

I will use the formula 2X to find how many bits I need to borrow.

21=2
22=4
23=8
24=16
25=32
26=64
27=128

I need to borrow 7 bits to create 113 subnets.
