How does one go about subnetting a Class B IP?

I have determind that I need to generate 60 subnets.

I think I have to borrow 6 bits, which would generate 62 subnets?

After that, I have no idea...anyone?

You would need to set your subnet mask to 255.255.252.0

You can run a subnet calculator and then it will tell you the IPs of each subnet.

yep, you should borrow at least 6 bits from the third octet.
Class B=>(N.N.H.H)

It lets you get (2^6)-2=62 subnets
the subnet mask is 255.255.252.0
and you get (2^10)-2=1022 hosts on each subnet
