So, fqm889 is completely correct, and I can verify this as well.

ipv6 address:

Change aa bb cc dd ee ff gg hh from heximal to decimal AAA BBB CCC DDD EEE FFF GGG HHH
Then you can find that AAA.BBB.CCC.DDD is your source and EEE.FFF.GGG.HHH is your destination of 'DoS' packets.
I am seeing the same IP source to multiple target addresses, and this now makes sense because the first 3 fields of ipv6 will always be the same as would the first three numbers of an IPv4 address like "192.168.0.X" on the private network.
The target number is the fourth field of the IPv6 address that's allocated to my device, and different devices will show different numbers here. Also, this part of the address is dynamic and changes over time, so it looks like the target changes every few days. Targets because of the randomness of IP addresses have appered to be benign things like a random mobile device, or addresses of goverment or banking organizations in other countries. In fact, as demonstrated by fmq889 none of these addresses are actually being reached from my network.
I would also like to add that ipv6 also provides for allocating 2 addresses for every device, and only the 2nd address or privacy extension/temporary address is tripping up the router.
In any case, I am wondering if the performance issues I see are related, and perhaps the router is trying to filter/block or otherwise uses resources tracking all these seeminly malignant calls, when they are actually perfectly legit traffic passing through the network.
I hope that Netgear will fix, but perhaps we all who are seeing this should try to contact them directly and let them know of the issue rather than hope they monitor user forums.
