Interestingly, looking through my logs for UDP 1434, I saw a sequential
scan of my subnet like so:
Jan 16 08:15:51 18.104.22.168,53 -> x.x.x.1,1434 PR udp len 20 33 IN
Jan 16 08:15:51 22.214.171.124,53 -> x.x.x.2,1434 PR udp len 20 33 IN
Jan 16 08:15:51 126.96.36.199,53 -> x.x.x.3,1434 PR udp len 20 33 IN
All from 188.8.131.52, all source port 53 (probably trying to
use people's DNS firewall rules to get around being filtered).
After that, I saw nothing until the storm started last night from many
different source IPs, which was at Jan 24 21:31:53 PST for me.
