MicroHAWK DHCP Base Address: Configuring 172.22.4.x

Registry Setting and Address Encoding

The MicroHAWK camera USB LAN service stores its DHCP base network in the Windows registry at HKLM\SYSTEM\CurrentControlSet\services\MicroscanUSBLAN. The relevant value is DHCPBase. Its default value, 0xc0a8bc00, represents 192.168.188.0 when the hexadecimal value is split into byte pairs and each pair is converted to decimal.

Configure the 172.22.4.x DHCP Base

1. Disconnect the camera.
2. Open Windows Registry Editor.
3. Navigate to HKLM\SYSTEM\CurrentControlSet\services\MicroscanUSBLAN.
4. Locate the DHCPBase value. The documented default is 0xc0a8bc00.
5. Set DHCPBase to 0xac160400 for the 172.22.4.0 base network. Do not change the final address number; it must remain 0.
6. Reconnect the camera so the new base address takes effect.

Verify the Address Change

After reconnecting the camera, confirm that its assigned address begins with 172.22.4. If the address does not change, reopen the same registry location and verify that DHCPBase contains exactly 0xac160400, then disconnect and reconnect the camera again.

Address Conversion Rule

To interpret the registry value, separate its eight hexadecimal digits into four pairs. Convert each pair independently to decimal and preserve the pair order. The fourth pair represents the final base-address octet and must remain 00 for this configuration.

0xac160400
AC  16  04  00
172 22  4   0
172.22.4.0
