I reached the limit of 32 IPs added to the blocked list.  However, persistent hackers are attacking my cameras from these subnets .

I want to block

159.138.0.0/16

94.74.0.0/16

18.163.0.0/16

52.33.0.0/16

163.171.0.0/16

35.0.0.0/16

54.0.0.0/16

122.0.0.0/16

119.0.0.0/16

All cameras are in a parental control group with all Child restrictions + the 32 added IPs/domains.  

I used to be able to shut off Internet access entirely for the group.  That worked perfectly for a year or so.  I could still do whatever I needed within my LAN/WLAN.  However, they appear to have pushed an update through the iCSee app (?) which now requires the cameras to contact the Internet for me to be able to view the camera feed.

My work-around was to keep Internet access off unless I needed to view the stream, then block whatever new IP had been communicating with the cameras during the few minutes they were accessing the Internet.  That is no longer an option as I have hit the 32 blocked addresses limit.

How to block more addresses?

I look forward to your feedback.  :)
