IPv6 in Denver
I have noticed that a Unifi gateway I manage for a family member offered that IPv6 was now available on WAN1. I clicked on it and it just automatically enabled it without a popup. Their network is vanilla, so I imagine this will be a benign change. However, they have been complaining about some periodic slowness, and I'm wondering if the stuff I have been reading about Europeans suffering slow IPv4 when IPv6 is available is happening here.
Most things I read about IPv6 are Europeans complaining that too many things do not yet support IPv6, or others complaining that IPv6 is just adding complication to a network if you have anything more than a vanilla setup. However, most of the posts saying IPv6 is not worth the hassle are from 2020-2021. I'm not seeing much in this space in 2025-2026.
First, it is surprising that Quantum Fiber is enabling IPv6 and I'm not reading much about it. Second, I'm wondering if now is the time to get on the bus, or just hold tight. Any strong opinions out there?
