Question
A technician is setting up a new workstation at a customer’s office. The office network has one public IP address and utilizes NAT for the internal network. In addition, DHCP is not used, so all IP addresses are manually provisioned. Which of the following IP addresses should the technician assign to the workstation?
A. 172.15.65.10
B. 175.16.20.3
C. 192.168.1.56
D. 193.167.35.4
Answer
C. 192.168.1.56
Explanation
When setting up a workstation in a network that uses Network Address Translation (NAT) and manually assigned IP addresses, it is crucial to choose an IP address from the private IP address ranges. Private IP addresses are designed for use within internal networks and are not routable on the public internet.
The private IP address ranges are:
- 10.0.0.0 to 10.255.255.255 (10/8 prefix)
- 172.16.0.0 to 172.31.255.255 (172.16/12 prefix)
- 192.168.0.0 to 192.168.255.255 (192.168/16 prefix)
Among the given options, the correct IP address to assign to the workstation is:
C. 192.168.1.56
This IP address falls within the 192.168.0.0/16 private IP address range, making it suitable for use in an internal network. The other options provided are public IP addresses and should not be used in this scenario:
- 172.15.65.10 is a public IP address, despite having a similar prefix to the private 172.16.0.0/12 range.
- 175.16.20.3 and 193.167.35.4 are both public IP addresses and are not part of any private IP address range.
By assigning the workstation a private IP address, such as 192.168.1.56, the technician ensures that the device can communicate within the internal network while the NAT system handles the translation between the private and public IP addresses. This configuration allows multiple devices to share a single public IP address, conserving the limited number of available public IPv4 addresses. When setting up workstations in a NAT network with manual IP provisioning, always choose an IP address from one of the three designated private IP address ranges.
