I read that most routers and switches support IPv6, but how they support the protocol differs. The article said that specific network hardware devices have dedicated network processors while others have general purpose processors, which are worse because those forward packets at a slower rate. How can I tell whether the devices on my network support IPv6 in the best way?

Thanks. We'll let you know when a new response is added.

My best suggestion would be to look up the Admin guides / White papers on the specific device you have questions about.
The manufacturers would be the best resource for what their devices support and how…

It's basically, you pay what you get for. Low end routers and devices have low end processors and parts.

Hi Yes, you are right, implementations are different. And for some devices it is important to know whether the processing is done in hardware or in software. Especially for devices such as routers and firewalls. There can be a combination. Some basic functions may be done in hardware, while other may be processed in software. The only one that can tell you is the vendor. Silvia
