On a Windows client, how can you display the DHCP server address from which the machine obtained its IP configuration?
-
AUse the Advanced Properties of TCP/IP
-
BUse IPCONFIG/ALL
-
CUse DHCPINFO
-
DPing the DHCP server
-
ENone of the above
Answer
Correct Answer: Use IPCONFIG/ALL
Explanation
Introduction: When troubleshooting dynamic addressing, technicians often need to confirm the identity of the DHCP server that leased an address to a Windows host. The command-line provides a concise, authoritative view. This question seeks the correct method to view that server address.
Given Data / Assumptions:
- Windows operating system environment.
- The client is configured for DHCP or has a DHCP lease history.
- We want to view the DHCP server address specifically.
Concept / Approach: The ipconfig /all output enumerates per-adapter details including DHCP Enabled status, DHCP Server, Lease Obtained, and Lease Expires. This output is the standard artifact requested in support tickets.
Step-by-Step Solution:
1) Open Command Prompt with appropriate privileges.2) Runipconfig /all and locate the active adapter.3) Read the “DHCP Server” field to identify the leasing server.Verification / Alternative check: Network engineers routinely ask for this output to validate DHCP scope, options, and server identity across Windows versions.
Why Other Options Are Wrong:
- Advanced Properties: GUI does not always expose the server address directly and varies by version.
- DHCPINFO: not a standard Windows utility.
- Ping the DHCP server: requires knowing the address already; not a discovery method.
- None of the above: incorrect because
ipconfig /allis valid.
Common Pitfalls: Looking at the wrong adapter (e.g., virtual NICs); ignoring that a statically configured adapter will not show DHCP fields.
Final Answer: Use IPCONFIG/ALL.
