I have started seeing a local ISP using IPs like 22.214.171.124/24. This unfortuantely falls into one of the unroutable IPs 126.96.36.199/3. I have changed it to 188.8.131.52/4 in order avoid blocking the IPs. I'm just wondering if anyone has experienced similar problem? Is there a upto date unroutable IP list out there?
