Yes, MikroTik RouterOS supports IPv6. RouterOS is the operating system that powers MikroTik devices and has incorporated support for IPv6 for several versions, allowing users to configure and manage networks that use this most recent version of the Internet Protocol.

IPv6 features in MikroTik RouterOS

1. IPv6 Address Configuration: RouterOS allows the configuration of IPv6 addresses on individual interfaces, as well as the configuration of IPv6 routes and gateways.
2. DHCPv6: Support for DHCPv6, which allows IPv6 addresses to be assigned dynamically to devices on the network.
3. IPv6 Firewall: RouterOS includes a firewall that supports specific rules for IPv6 traffic, allowing network administrators to implement robust security policies to protect their networks.
4. IPv6 tunnels: Support for various types of IPv6 tunnels, including 6to4 and 6in4, which are useful for the transition from IPv4 to IPv6.
5. Router Advertisements: RouterOS allows you to configure Router Advertisements for address autoconfiguration on network devices, a key feature of IPv6.
6. Neighbor Discovery: Implementation of the Neighbor Discovery (ND) protocol for the detection and maintenance of information about devices on the network.

Considerations for IPv6 Implementation

• License: Ensure that your MikroTik device has an appropriate license that allows full use of IPv6 functionalities, especially in production environments.
• Training and Knowledge: Configuring IPv6 can be more complex than IPv4 due to differences in addressing and traffic management. It is recommended that network administrators become familiar with the specifics of IPv6 before deploying it in critical environments.
• Device Support: While RouterOS supports IPv6, it is important to also verify IPv6 support on all devices on the network to ensure a smooth deployment.

MikroTik has continued to update and improve IPv6 support in RouterOS, so users can take advantage of this technology to modernize their networks and prepare for future connectivity needs.
