How to Configure DHCP on a Computer?

DHCP (Dynamic Host Configuration Protocol) is used to automatically assign IP addresses, allowing devices to connect to a network with minimal configuration. The following sections explain how to enable DHCP on Windows and macOS systems.

1. Configure DHCP on Windows​

  1. Open the Network Connections Panel
  • Press Win + R, type ncpa.cpl, and click OK.
  1. Select the Network Adapter
  • Right-click the target network connection (such as Ethernet or Wi-Fi) and select Properties to configure IPv4.
  • Select Internet Protocol Version 4 (TCP/IPv4) and click Properties.
  • Select Obtain an IP address automatically and Obtain DNS server address automatically.
  • Click OK.
  1. Configure IPv6 (Optional)
  • Select Internet Protocol Version 6 (TCP/IPv6) and click Properties.
  • Select Obtain an IPv6 address automatically and Obtain DNS server address automatically.
  • Click OK.

2. Configure DHCP on macOS​

  1. Open Network Settings
  • Click the Apple menu → System Preferences → Network.
  • Select the active connection (such as Wi-Fi or Ethernet) from the left panel and open the advanced settings.
  • Click Advanced → select the TCP/IP tab.
  • In the Configure IPv4 drop-down menu, select Using DHCP, then confirm and save the settings.
