Unless you network has a specific requirement for IPv6, very few do, you can safely disable IPv6.

Great. Lets all put strain on the CGN because we're stuck in a meme of IPv6 failure and don't actually understand how modern high speed networks operate.

I get it, hate is normal. But really, IPv6 is unlikely to be the root cause problem of whatever you're trying to fix. And, you've just broken a number of service relationships implemented as IPv6 overlay networks. It's not windows of course, but "find my mac" and other services operate (or used to) in ULA space as does the Apple "hide my IP" service.

This is good advice in as much as it explains what to do. Thats the same as good advice on how to disable your speed limiter, or disable your smoke alarm permanently, or whatever else it is people think they want to do in a 'leopard ate my face' moment.

Disabling IPv6 should be a last resort.

That's not the point of the article, this is simply a barely documented equivalent to the Linux `sysctl` one liner for those testing or who need it and hence why I shared it, not sure where that all came from.

Edit: You seem to have edited your response.

Oh come on. You mean pMTU mismatch, bad frag, ICMP blocking, stupid firewall NAT tricks, CGN drop due to rapid address rollover, mis-GEO don't happen in IPv4?

Bad routes are a daily occurrence. V6 isn't responsible for BGP flakiness.

No, it seems like I have attracted the hive again ;).

This is not something you should do.

Correct.
