Re: Overly Gloom and Doom 90's Predictions
Let me start with a disclaimer -- I'm not against IPv6 even a little. But...
"IPv6 doesn't really have any serious disadvantages over IPv4"
I'm not sure what you consider "serious", but in my view the biggest pain point with IPv6 is the discoverability issue. Without taking active measures to mitigate the problem, IPv6 reveals far more about my devices and network than I'm comfortable with. I count this as a disadvantage.
Also, IPv6 has a lot more moving parts than IPv4, and I'm nowhere near confident that I know enough to be able to secure such a network adequately. While that will be resolved once I reach the summit of that learning curve, the extra complexity of IPv6 certainly counts as a disadvantage in this sense.
