Subnetting Assignment

The ABC Corp. has been assigned the class B address of 172.123.4.0/24.
They have offices in 3 different locations:
• New York with 30 workstations
• Chicago with 40 workstations
• District of Colombia with 25 workstations

It is anticipated that they will grow by 20% within the next few years, before they have to switch over to IPv6 addressing. They are also planning to expand to Dallas with 10 workstations.

• Network Address (6%)
