- Assume an ISP owns address block 128.211.0.0 / 16
- There are 4 Networking companies (A, B, C, D) gets Internet services from the ISP with each has following number of PCs respectively: 10, 7, 3, 10, 10
- The ISP assigns 128.211.0.16/28 block to Company A. Then PCs in Company A will have IPs ranging from 128.211.0.16 through 128.211.0.31.
- The ISP assigns /29 block neighbor IP addresses to Company-B. Then PCs in Company B will have IPs ranging from 128.211.0.32 through 128.211.0.39
- The ISP assigns /29 block next neighbor IP addresses to Company-C,
- The ISP assigns /29 block next neighbor IP addresses to Company-D,
Calculate the IP address range for Company C and D similar to range provided for Company A and B
