Question

Assume that a large number of consecutive IP addresses are available starting at 198.16.0.0 and suppose that two organizations, A, B, C, and D, request 4000, 2000, 4000, and 8000 addresses, respectively, in that order. For each of these, give the first possible IP address within the assigned subnet, the last possible IP address within the assigned subnet, and the subnet representation in slash notation (w.x.y.z/s) Please enter your answers using the exact format shown in the sample row. Do not include any spaces. First possible IP Address in Last possible IP Address in Assigned subnet Subnet representation using Slash Notation Organization Assigned subnet Sample 100.100.10.0 100.100.10.255 100.100.10.0/24 nswer Organization Organization Organization Organization

Explanation / Answer

Organisation A the requested addresses are 4000,the host portion bits will be 12 i.e. 212 = 4096, First IP address would be 198.16.0.1 Last IP address would be 198.16.00001111.10100001 or 198.16.15.161 The Subnet representation would be 198.16.0.0/20 Organisation B requested 2000 addresses so the host bits would be 11 i.e 211 = 2048 First IP address would be 198.16.16.1 Last IP address would be 198.16.00010111.11100001 or 198.16.23.225 The subnet mask would be 198.16.16.0/21 Organisation C requested 4000 address so the host bits would be 12 i.e 212 = 4096 First IP address would be 198.16.48.1 Last IP address would be 198.16.0011111111.10100001 or 198.16.63.161 Subnet mask would be 198.16.48.0/20 Organisation D requested 8000 address so the host bits would be 13 i.e. 213 =8192 First IP address would be 198.16.96.1 Last IP address would be 198.16.01111111.01000001 or 198.16.127.65 Subnet mask would be 198.16.96.0/19
