Lab 7: Subnezting and Supernettlng Exercise 1 Defining a Subnet Addressing Scheme In this exercise. you will work in a group to define a suhnct addressing scheme based on one of the following scenarios. For each scenario. you will define the following: - A subnct mask. a A range of valid network IDs. I A default gateway for hosts on each suhnet. Scenario 1 You have been assigned one class B address ol‘ l3 l .l07.0.0 by the luteerC. Your private internet currently has five suhnets. Each suhnet has approximately 300 hosts. Within the next year the number of suhncls will triple. The numhcr of hosts on three or the suhnets could increase to as many as 1000. l. How many hits did you use for the suhnet mask? 2.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
