How to disable APIPA
A Windows-based computer that is configured to use DHCP can automatically assign itself an Internet Protocol (IP) address if a DHCP server is not available. For example, this could occur on a network without a DHCP server, or on a network if a DHCP server is temporarily down for maintenance.
Read more about APIPA on the What's APIPA? page.
You may want to disable it in any of the following cases:
- Your network uses routers.
- Your network is connected to the Internet without a NAT or proxy server.
To disable automatic address configuration do the following:
Windows 2000/XP/2003
- Open Registry Editor.
- In Registry Editor, navigate to the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ Services\Tcpip\Parameters\Interfaces\adapter_name - Create the following entry: IPAutoconfigurationEnabled: REG_DWORD
- Assign a value of 0 to disable Automatic Private IP Addressing (APIPA) support for the selected network adapter.
- Close Registry Editor.
Note: You must be logged on as an administrator or a member of the Administrators group in order to complete this procedure.
If the IPAutoconfigurationEnabled entry is not present, a default value of 1 is assumed, which indicates that APIPA is used. If multiple adapters are installed, you can disable APIPA for all installed adapters by setting the IPAutoconfigurationEnabled entry to 0 at the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ Services\Tcpip\Parameters
Windows 98/ME
- Open Registry Editor.
- In Registry Editor, navigate to the following registry key:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\ Services\VxD\DHCP - Create the following entry:
- IPAutoconfigurationEnabled: REG_DWORD
- Assign a value of 0 to disable Automatic Private IP Addressing (APIPA) support for the selected network adapter.
- Close Registry Editor.
