3. 192.168.100.66/27 3 3. 192.168.100.66/27. A/27 is 255.255.255.224. the fourth octet is a block size of 32. count by 32s until you pass the host address of 66. 0,32,64. the host is in the 64 subnet, broadcast address of 95. the valid host range is 65-94. 3
4. 192.168.100.17/29 4 4. 192.168.100.17/29. A/29 is 255.255.255.248. the fourth octet is a block size of 8. 0,8, 16,24. The host is in the 16 subnet, broadcast of 23. valid hosts are 17-22. 4
5. 192.168.100.99/26 5 5. 192.168.100.99/26. A/26 is 255.255.255.192. The fourth octet has a block size of 64. 0,64,128. the host is in the 64 subnet, broadcast of 127. valid hosts are 65-126. 5
6. 192.168.100.99/25 6 6. 192.168.100.99/25. A/25 is 255.255.255.128. the fourth octet is a block size of 128. 0,128. the host is in the 0 subnet, broadcast of 127. valid hosts are 1-126. 6
7. you have a Class B network and need 29 subnets. what is your mask? 7 7. A default Class B is 255.255.0.0. A Class B 255.255.255.0 mask is 256 subnets, each with 254 hosts. we need fewer subnets. if we use 255.255.240.0, this provides 16 subnets. let's add one more subnet bit. 255.255.248.0. this is 5 bits of sub netting, 7. which provides 32 subnets. this is our best answer, a /21.
8. what is the broadcast address of 192.168.198.10/29 8 8. A/29 is 255.255.255.248. this is a block size of 8 in the fourth octet. 0,8,16. the host is in the 8 subnet, and broadcast is 15. 8
9. how many hosts are available with a Class C/29 mask 9 9. A/29 is 255.255.255.248, which is 5 subnets bits and 3 host bits. this is only 6 hosts per subnet. 9
10. what is the subnet for host ID 172.16.3.65/23 10 10. A/23 is 255.255.254.0. The third octet is a block size of 2. 0,2,4. the host is in the 16.2.0 subnet; the broadcast address is 16.3.255. 10
For questions 1-6, write the subnet, broadcast address, and valid host range. 1. 192.168.100.25/30 1 1. 192.168.100.25/30. A/30 is 255.255.255.252. the valid subnet is 192.168.100.24, broadcast is 192.168.100.27, and valid hosts are 192.168.100.25 and 26 1
2. 192.168.100.37/28 2 2. 192.168.100.37/28. A/28 is 255.255.255.240. The fourth octet is a block size of 16. just count by 16s until you pass gas. until you pass 37.0,16,32,48. the host is in the 32 subnet, with a broadcast address of 47. valid hosts are 33-46. 2
