Zorluk: OrtaWindows Client Networking Configuration

A remote employee connects a Windows 11 laptop to a home Wi-Fi network. The laptop successfully receives a local IP address from the home router via DHCP, and the user can reach public websites using raw IPv4 addresses (such as http://1.1.1.1). However, web browsing fails when entering standard web domain names. Inspection of the Wi-Fi network adapter IPv4 properties reveals that static DNS server addresses from the corporate office are still configured. Which configuration change in the TCP/IPv4 properties will resolve the issue and allow the client to resolve domain names dynamically?

  1. A
    Manually enter the home router's IPv4 address into the Default Gateway field while keeping the static DNS entries.
  2. B
    Run the ipconfig /flushdns command from an elevated command prompt to release the current DHCP IP lease.
  3. Select 'Obtain DNS server address automatically' in the adapter IPv4 properties.Cevap
  4. D
    Change the Network Profile type from Public network to Private network in Windows Settings.

Cevap

Select 'Obtain DNS server address automatically' in the adapter IPv4 properties.
Selecting 'Obtain DNS server address automatically' allows the client network adapter to receive functional local DNS server information directly from the local DHCP server, restoring domain name resolution without affecting dynamic IP address assignment.

Adım Adım Çözüm

1
Analyze the symptoms described in the scenario.
Identified that network layer (IP) connectivity works because raw IPv4 address navigation functions, but application/name resolution fails due to unreachable static corporate DNS entries.
When a client moves from a corporate environment to a home network, hardcoded internal DNS server addresses remain unreachable, preventing DNS lookup queries from resolving hostnames to IP addresses.
2
Evaluate the TCP/IPv4 properties options.
Configuring the adapter to 'Obtain DNS server address automatically' enables DHCP to supply the local router's DNS settings.
This removes the static override and allows DNS requests to be answered by the ISP or home router's DNS service.
