What is Bind IP to MAC and how to use it?

Support Model :
  • Tags :

While DHCP sever dynamically assign a IP address every time a device connects to the network, Bind IP to MAC could avoid IP address changing with reconnection. Once a specified IP address and a device's MAC address are bound, the IP address will be reserved for the device and the device will get that IP address every time it connects to the router. This not only make it easier for the Administrator to manage critical devices, but also is a method to manage the LAN clients.

   

 

 

Set up IP Bind List

To set up IP Bind List, go to LAN >> Bind IP to MAC, add a MAC address from the ARP table:

1. Select a MAC address.
2. Click Add to add it to the IP Bind List.
3. Click OK to save.

   

You could also manually enter the IP address and MAC address and add them to the IP Bind List.

1. Enter the IP Address and MAC Address.
2. Click Add to add them to IP Bind List.
3. Click OK to save.

   

 

 

Normal Mode

When we enable Bind IP to MAC, a device in IP Bind List will always get a specified IP address every time it connects to the network. As for an unlisted device, it will get a an available IP address out of IP Bind List.

To enable Bind IP to MAC in normal mode, go to LAN >> Bind IP to MAC, and select Enable.

   

 

 

Strict Mode

If we enable Bind IP to MAC in strict mode, the devices listed in the IP Bind List will get the reserved IP address, and only the device listed in the IP Bind List are allowed to access the Internet. Other devices in the ARP table but not listed in IP Bind List will be blocked by the router and cannot access the Internet.

   

To enable Bind IP to MAC in strict mode, go to LAN >> Bind IP to MAC, and select Strict Bind.

   

Since 3.8.5 version firmware, network administrator can set the Strict Bind to the specific subnet only. On the selected subnets, only the client whose MAC address is on the bind list will be able to connect; on the unselected subnets, router will assign the IP address to every client. Please notice that if none of the subnet is selected, then router will consider to apply strict bind to every subnets, every LAN device must be in the IP bind table to access Internet.

   

 

 

Backup and Restore IP Bind List

Since 3.7.4.2 version firmware, network administrator can backup the IP Bind List of Vigor router, and restore it to any other Vigor router which supports this feature. Just few clicks on Backup and Restore buttons, then the IP Bind List is saved to your computer, and transferred to another Vigor router.
