It’s not official, but you don’t always need to replace Cat5 cable with Cat6 to support 10Gbps Ethernet. Cat5 might only get you a quarter of the range of Cat6 on a good day, but since the range of Ethernet is 300 feet you would need a really big house to have cables that were too long. But generally the real question is how often the extra speed would give you a real measurable advantage. If it’s only a few times per month then it’s probably not worth the extra subscription cost.
