Recap - Plan a Network

Lesson 37 of 46 in Coddy's IP Addressing and Subnetting course.

Challenge

Medium

Plan a block on your own. From 172.31.4.0/24, allocate for three teams using VLSM, largest first:

Team A: 60 hosts
Team B: 25 hosts
Team C: 10 hosts

Print the three allocations in CIDR notation, one per line, in that order.

Expected output:

172.31.4.0/26
172.31.4.64/27
172.31.4.96/28
