. If an ISP offers a /20 IPv4 address block for $3480 per month and a /21 address block for $2046 per month, which one has the cheaper cost per usable address? Show your work.   2. a. What is the MTU of a network? Explain why fragmentation is necessary to accommodate heterogeneous networks with different MTUs.   If an IPv4 datagram with a payload of 2720 bytes must be sent over a network with an MTU of 700 bytes, how many fragments at minimum should be sent? Show your work.
