For completeness, I was also in the thread early with a need to disable it. Short version: my ISP does not (yet) provide IPv6 connectivity, and my router was supplied by the ISP so already had IPv6 disabled. I was having trouble with DNS failures due to bind9 not finding an IPv6 route out of the network and giving up, even though the requested host also had an IPv4 address. I was advised that disabling IPv6 in the kernel was the final fix, so I did that to the two Raspberry Pis which were having the problems, mostly of finding RPi apt repositories. No good. I had to disable it individually in both bind9 and apt to get reliable IPv4 lookups. I left the thread at this point. -- Joe
