Recently, there has been much talk about the Cloudflare BGP blunder and others. The Network Collective even did a video about such things. But did you know there was one involving the entire /12 of IPV6 space? Airtel AS9498 announced the entire IPv6 block 2400::/12 for a week and no-one noticed. Someone typed a /12 instead of a /127.
So why did no one notice? I think part of it is due to the low usage of v6 space. Sure, all kinds of people claim stats on IPV6 usage. They talk about X number of traffic is v6, etc. There is a difference between users and connections. A connection may not actually represent unique users.
Secondly, people are used to IPV6 being buggy. I know many ISPs who disabled v6 as part of their troubleshooting steps.
I know there will be several folks who jump all over me about IPV6 being the wave of the future and we all should be using it. Yes, we should, but there is no huge hurry when it comes to business cases.
