Thanks to a tip to investigate 199.68.199.178 I discovered that the Caphaw network
I looked at yesterday is much bigger than I thought. The following IPs and domains can all be regarded as malicious (.SU domains are normally a dead giveaway for evil activity).
The recommended blocklist is at the end of the post (
highlighted).
These are the hosts involved either now or recently with hosting these Caphaw domains:

identified doing this before):
