The calls to transition to IPv6
are getting more intense now that IPv4 Internet address blocks have officially run out. Networks are morphing into a mix of both IPv4 and IPv6 addressed devices, or in some cases, entirely IPv6 addressed devices. To monitor effectively your network management solution (NMS) must be designed to support all of these devices.
Have you checked your existing management tools to be sure they are IPv6 compatible? Next generation NMS tools
need to do more than just be updated to support IPv6, they need to accommodate the changing methods of managing IPv6 networks. Make sure your network management and monitoring software is ready to handle these five potential issues with the migration to IPv6.
1. No longer will traditional IP scanning work in IPv6 environments, now different methods to discover inventory will need to be incorporated into the network discovery process. Your solution should incorporate event based discovery to auto capture IPv6 devices, since traditional IP scanning won’t work.
2. Dual stack networks need the ability to poll each device with either their IPv4 or the IPv6 addresses. Your management solution should have the flexibility to toggle the polling between any IP address.
3. Organizing and mapping devices by subnet is one of the most popular existing methods for mapping your network, but this approach will have limited value in IPv6 networks. Your management solution should offer dynamic groupings and mappings based on location and a multitude of other attributes on a device to ensure that automated mappings continue to be a valuable feature.
4. Many of the existing user interface systems for monitoring tools have data fields with pre-set lengths and data integrity checks for IPv4 address types and may not work for IPv6. Many IT managers who have neglected to check before converting have reported that analyzers and the other monitoring tools tend not be IPv6 compatible. Make sure your monitoring tools can handle IPv6 address types.
5. IPv6 will lead to larger networks that directly address more network devices, increasing the overall complexity of monitoring and management. Ensure your management solution will continue to be easy to use as more diverse devices start to populate the network.
