Configuring IPv4 in Windows: A Comprehensive Guide

Accessing the Network and Sharing Center

• The tutorial introduces lesson number 8, focusing on configuring IPv4 in Windows, DHCP, and ARP.

• Users can access the Network and Sharing Center by pressing the Windows key + I to open the configuration application, then selecting "Network & Internet."

• From the Network and Sharing Center, users can view network configurations and choose between manual or automatic IP address configuration.

Manual Configuration of IPv4 Address

• To manually configure an IPv4 address, navigate to "Change adapter settings," right-click on the desired adapter, select "Properties," then choose "Internet Protocol Version 4" (IPv4).

• In the IPv4 properties window, users can set their IP address, subnet mask, and default gateway; these concepts will be explored further in later lessons.

Automatic Configuration Using DHCP

• Devices can automatically obtain an IP address using DHCP; this is enabled by selecting "Obtain an IP address automatically" in the IPv4 properties.

• Once configured for DHCP, a host will locate a DHCP server that assigns necessary network configurations for communication.

Verifying IP Configuration

• To verify IPv4 configuration via command line, press Windows key + R to open Run dialog box. Type cmd to launch Command Prompt.

• Use ipconfig command to display current IP address information including subnet mask and default gateway.

• For more detailed information about network configuration including MAC addresses and DNS servers, use ipconfig /all.

Testing Connectivity with Ping Command

• The ping command tests connectivity by sending echo packets to a remote device; type ping [IP address] in Command Prompt for testing.

• Results show statistics such as packets sent/received/lost which help assess network reliability.

Understanding ARP (Address Resolution Protocol)

• ARP is used to determine destination MAC addresses associated with destination IPv4 addresses; it maintains an ARP table/cache.

• To examine the ARP cache on a Windows host, use the command arp -a in Command Prompt.
