How to modify the IP address and the MAC address of the Registry
I. How to change the IP address
C:/> ipconfig (use the ipconfig command to check the IP address before the change)
Windows 2000 IP configuration
Ethernet Adapter local connection:
Connection-specific DNS suffix .:
IP address ......: 10.1.1.94 (the IP address before the local connection is changed)
Subnet Mask ......: 255.255.255.0
Default Gateway ......: 10.1.1.254
C:/> netsh (entering the Setting Mode)
Netsh> Interface
Interface> ip
Interface ip> set address "Local Connection" static 10.1.1.111 255.255.255.0 10.1.1.254
Interface ip> exit
The SET command described above is explained as follows:
Set address-set the IP address and default gateway of the specified interface.
Set DNS-set the DNS server mode and address.
Set wins-set the WINS server mode and address.
C:/> ipconfig (use the ipconfig command to check whether the change is successful)
Windows 2000 IP configuration
Ethernet Adapter local connection:
Connection-specific DNS suffix .:
IP address ......: 10.1.1.111
Subnet Mask ......: 255.255.255.0
Default Gateway ......: 10.1.1.254
Generally, the IP address and MAC address can be directly changed in the local connection attribute of the network neighbor.
2. How to modify Mac in the Registry
1. Use software modification
SMAC professional V2.0 cracked version
2. Modify Nic attributes
If your Nic uses the RealTek rtl8139 chip, you can modify the MAC address in the NIC attribute so that the MAC address in the registry will change as follows:
In win2003/XP/2000, click "start"/settings/control panel, double-click "system", and click "hardware"/Device Manager, expand "network adapter" in the Device Manager, right-click the NIC whose MAC address you want to modify, and select "properties". Click the "advanced" tab. Under "properties, click the network address project (Figure 2) and enter the MAC address value (for example, 020202020202) under the "value" on the right ), note that 12 digits or letters must be entered consecutively (do not enter-in the middle). After restarting the computer, the modification will take effect. The Mac modification method under Win98 is similar to the above method.
If you want to restore the MAC address in the Registry to its original state under win2003/XP/2000 after modification, you can select the "Network Address" item, select "not exist" as the value on the right and restart the instance. In Win98, select "not displayed ".
3. modify it in the Registry
For non-rtl8139 NICs, you can directly modify the Mac in the registry. Note: Before you modify the registry, back up the registry.
① Search for driverdesc under the primary key of HKEY_LOCAL_MACHINE/system/CurrentControlSet/control/class/{4d36e972-e325-11ce-bfc1-08002be10318}/0000, 0001, 0002, And. The content is the description of the NIC to be, for example, "RealTek rtl8029 (AS)-based PCI Ethernet Adapter ".
② Add a string named networkaddress under it and set its value to the MAC address you want (note that the address is still written consecutively ). For example, 00e0dde0e0e0.
③ Add a primary key named networkaddress to NDI/Params and add a string named default under the primary key. The value of this string is the MAC address you want to set and must be written continuously, for example, 000000000000. (In fact, this is only the "Initial Value" in the advanced attribute mentioned later. The actual MAC address used depends on the networkaddress parameter mentioned in. Once this parameter is set, in the future, the value in the advanced attribute is the value given by networkaddress rather than the value given by default .)
④ Add a string named paramdesc under the primary key of networkaddress. The function is to specify the description of the primary key of networkaddress. The value can be named by yourself, for example, "network address ", in this way, the network address option will appear in the Advanced properties of the network adapter, that is, the new networkaddress you just added in the registry. You only need to modify the MAC address here. Add a string named optional with the value set to "1". When you select the network address option in the Advanced properties of the network adapter, the "no" option will appear on the right.
⑤ Restart your computer, open the network neighbor attributes, double-click the corresponding Nic item, and you will find an advanced network address setting item, it can be used to directly modify the MAC address or restore the original address.
