For Organization D, we establish a starting IP address by taking the binary of the last IP address used for Organization C and using the first bit that was not used as a host for Organization C. This would be the 15th bit from the right. Therefore, we can establish the binary representation of the starting IP address for Organization D as: 11000110 00010000 01000000 00000000 This is represented in decimal as: 198.16.64.0 Organization D is requesting 8000 addresses, so the nearest power of 2 value would be 13 (8192). We now take our above starting address and convert host bits to display our last IP address for Organization D as follows (binary): 11000110 00010000 01011111 11111111 We now convert this to decimal: 11000110 = 198 00010000 = 16 01011111 = 95 11111111 = 255 Therefore, our last IP address for Organization B is:
CS 2204: UNIT 5 WRITTEN ASSIGNMENT 16 198.16.95.255 and since we used 13 host bits our mask will be (32-13): 198.16.64.0/19 Q3. A router R has the following distance-vector table: Destination Cost Next hop A 2 R1 B 3 R2 C 4 R1 D 5 R3 R now receives the following report from R1 (the cost of the R–R1 link is 1): <dest: A, cost: 1>, <dest: B, cost: 1>, <dest: C, cost: 4>, <dest: D, cost: 4>. Give R’s updated table after it processes R1’s report. For each entry, give a brief explanation. For Destination A and C, R1 factors in per Next hop. For Destination B and C, next hop is not R1. Therefore, based on this and R-R1 link is 1:

### What students are saying

• 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.
