Consider a subnet with the block 125.119.40.192/26.

(A) [2 point] Write out the IPv4 address 125.119.40.192 in binary.

(B) [2 point] Write out the mask for this block in binary.

(C) [2 points] What are the first and last addresses in this block? Write this in dotted decimal notation only.

(D) [4 points] Suppose an ISP wants to make four subnets from this block, with each block having the same number of IP addresses. Give the blocks (using the a.b.c.d/ x notation) for these four subnets.
