    Study Notes

    Understanding the ipconfig Command

    • The ipconfig command is a useful tool for checking and troubleshooting a computer's IP configuration.

    • Using ipconfig by itself displays basic IP information, including:

      • IP address
      • Subnet mask
      • Default gateway

    • The ipconfig /all command provides more detailed IP information, including:

      • DHCP enabled status
      • Auto-configuration enabled status
      • IPv4 address information
      • Subnet mask
      • Default gateway
      • DHCP and DNS server addresses

    Identifying DHCP Enabled Status

    • The DHCP enabled line indicates whether the network interface card is configured to obtain an IP address from a DHCP server.
      • "Yes" indicates that DHCP is enabled.
      • "No" indicates that DHCP is disabled, and the IP address is statically configured.

    Examining Static IP Information

    • When statically configuring an IP address, the DHCP enabled line will show "No."
      • The IP address, subnet mask, default gateway, and DNS server address will be the values manually assigned.
      • DHCP server addresses will be missing as the system is not relying on a DHCP server.

    Understanding Automatic Private IP Addressing (APIPA)

    • If a computer is unable to obtain an IP address from a DHCP server, it might use APIPA.
    • Computers using APIPA will have an IP address in the 169.254.0.0 range with a subnet mask of 255.255.0.0.
    • When you see an APIPA address, it means that the computer could not find a DHCP server.

    Utilizing ipconfig For Troubleshooting

    • ipconfig /renew command can be used to request a new IP address from a DHCP server.

    • The ipconfig /release command can be used to release any IP address currently assigned to the network interface card.

    • If a user reports they cannot connect to the internet:

      • First, use ipconfig /all to examine the IP configuration.
      • Check for the DHCP server IP address to determine if the computer is able to communicate with the DHCP server.
      • If the computer has an APIPA address, it suggests that the DHCP server is unavailable.

    Recap

    • The ipconfig command provides a powerful way to check and troubleshoot network connectivity issues.
    • By understanding the different outputs and options, you can quickly and effectively diagnose and resolve IP configuration problems.
