To finish our visual, we label all the corners and designate what the prefix is for each address space. These
are our leftover, unused subnets.
Remember, not every student will care for the visual way of representing VLSM. Many prefer to simply
do it by hand. In addition, this visual method can be difficult with larger address spaces. Imagine trying to
do this same exercise with a 10.0.0.0/8 address space and eight levels of subnetting. It would not be
impossible, but it also would not be very effective. However, I have found that, for some students, the
“light comes on” when I use a visual representation for VLSM.
