To divide the subnet 192.165.1.192/26 into three subnets as described, use the following:
1. Infrastructure Subnet: Supports 14 nodes
- Network Address: 192.165.1.192/28
- Usable IP Range: 192.165.1.193 to 192.165.1.206
- Subnet Broadcast Address: 192.165.1.207
2. Public Services Subnet: Supports 30 nodes
- Network Address: 192.165.1.208/27
- Usable IP Range: 192.165.1.209 to 192.165.1.238
- Subnet Broadcast Address: 192.165.1.239
3. Private Services Subnet: Supports 14 nodes
- Network Address: 192.165.1.240/28
- Usable IP Range: 192.165.1.241 to 192.165.1.254
- Subnet Broadcast Address: 192.165.1.255
Next, configure the ISC DHCP server as follows:
- DHCP Server IP and DNS Server IP (for all three subnets): 192.165.1.193
- Default and Max Lease Time: One week (604800 seconds)
- Domain Names:
- Infrastructure Subnet: infra.165pro.net
- Public Services Subnet: pub.165pro.net
- Private Services Subnet: prv.165pro.net
