Notes

  1. Because the second and third usable IP addresses (204.153.51.19, 204.153.51.20) on this network are in-use by the customer, OIT is instead using IP addresses 204.153.51.29 and 204.153.51.30 for OIT's network infrastructure.

  2. Because the second and third usable IP addresses (204.153.51.74, 204.153.51.75) on this network are in-use by the customer, OIT is instead using IP addresses 204.153.51.76 and 204.153.51.77 for OIT's network infrastructure.
