NETW202 Week 6 Lab Report 4 bits would need to be borrowed ( 2…4…8. ..16), leaving 20 bits for host idenﬁcaon. (2 20 - 2) 1,048,576 – 2 = 1,048,574 usable hosts per subnet. 14) You are given the Class A network address 10.0.0.0. From this network, if you needed to create 20 subnets, how many bits would need to be borrowed at a minimum, and how many hosts could you have per subnet? 5 bits would need to be borrowed ( 2…4…8. ..16), leaving 19 bits for host idenﬁcaon. (2 19 - 2) 524,288 – 2 = 524,286 usable hosts per subnet. 15) You are given the Class A network address 10.0.0.0. From this network, if you needed to create 40 subnets, how many bits would need to be borrowed at a minimum, and how many hosts could you have per subnet? 262,142 per subnet 16) You are given the Class A network address 10.0.0.0. From this network, if you needed to create 80 subnets, how many bits would need to be borrowed at a minimum, and how many hosts could you have per subnet? 7 bits, 131,070 per subnet Task 2: Now that you have pracced the subneng process, please complete the problems below. Be sure to show your work: a. You have been given the address 201.110.20.0 by your ISP. You need to create 5 subnets. How many bits minimum would you need to borrow? 5 subnets = (2 = 1, 4 = 2, 8 = 3) 3 bits are needed (1 points each) b. How many usable hosts per subnet will you have? (2 5 ) – 2 = 30 hosts (1 points each) c. You have been given the address 150.30.0.0 by your ISP. You want to create 50 subnets. How many bits minimum would you need to borrow? 50 subnets = (2 = 1, 4 = 2, 8 = 3, 16 = 4, 32 = 5, 64 = 6) 6 bits are needed (1 points each) d. How many usable hosts per subnet will you have? (2 10 ) – 2 = 1022 hosts (1 points each) Calculang Subnet Masks Lab (12 points) Write a paragraph (a minimum of ﬁve college-level sentences) below that summarizes what was accomplished in this lab, what you learned by performing it, how it relates to this week’s TCOs and other course material, and just as importantly, how you feel it will beneﬁt you in your academic and professional career. (4 points) In this lab, I learned how to calculate subnet masks. By that I mean I learned how to determine the subnet mask in binary with a speciﬁc network preﬁx number. I learned how to determine the borrowed bits for an IP address and the block size. Once knowing how to ﬁgure those things out ﬁguring out how to get the host range is a breeze. This lab was good pracce for determining and calculang subnet by using a lot of simple addion. This is good to know in the ﬁeld because it helps with seng up networks. For the Calculang Subnet Masks Lab, you must show your work in ﬁnding the needed subnet mask and host addresses. A missing or incorrectly calculated queson number will earn zero points. Copy and paste the following screenshots from your Calculang Subnet Masks Lab or worksheet below. Task 1: Paste your answer to problem 12 below. (.5 point) 12) Given a Class A network with the /29 preﬁx, determine the subnet mask in binary and decimal. Then calculate the maximum number of hosts it can support. Class A Default: 11111111.00000000.00000000.00000000 Binary: 11111111.11111111.11111111.11111000 Decimal: 255.255.255.248
