Yes, on MikroTik devices it is possible to assign both an IPv4 address and an IPv6 address to the same network interface.

This is common practice in dual stack configurations, which allow both protocols to operate simultaneously on the same network.

We explain how you can do it:

Step 1: Access the MikroTik Router

You can access your MikroTik device via WinBox, WebFig or SSH, depending on your preference and access settings.

Step 2: Assign the IPv4 Address

1. Navigate to the IP > Addresses section.
2. Click the “+” button to add a new IP address.
3. Enter the IPv4 address you want to assign and select the appropriate interface. For example, you can enter 192.168.1.2/24 and select ether1 or the corresponding interface.

Step 3: Assign the IPv6 Address

1. Go to the IPv6 > Addresses section.
2. Click the “+” button to add a new IPv6 address.
3. Enter the IPv6 address you want to assign and select the same interface you used for IPv4. For example, you can enter 2001:db8::1/64 and also select ether1.

Step 4: Verification and Testing

After assigning addresses, it is important to verify that both are configured correctly and that the interface can communicate using both protocols.

You can do this using tools like ping from MikroTik itself or from other devices on the network to ensure that the interface responds to both IPv4 and IPv6 requests.

Additional considerations

• Security: Make sure you properly configure firewall rules for both protocols to protect your network.
• Routes: Verify that the routes for IPv4 and IPv6 are configured correctly to allow the desired traffic through your network.
• Dual Stack: When working in a dual stack environment, it is vital to maintain consistent configuration and management to avoid connectivity or security problems.

Assigning IPv4 and IPv6 addresses to the same interface allows MikroTik devices to handle traffic over both protocols, easing the transition to IPv6 while maintaining compatibility with systems that still use IPv4.
