I noticed on a few firewall scripts there was a section to block reserved IP's. Unfortunately now that @home is no longer around cox was issued a large portion of the 068/8 network. Also Quest owns a large portion of 067/8 network. Most of the firewall scripts that block the IANA reserved list (http://www.iana.org/assignments/ipv4-address-space) have not been updated for over a year. So I took the list and tried to make a new block list. Any comments on my subnet masks is greatly appreciated (I make mistakes).
Here is the IANA reserved list: 00.0.0.0/8 01.0.0.0/8 02.0.0.0/8 05.0.0.0/8 07.0.0.0/8 10.0.0.0/8 14.0.0.0/8 23.0.0.0/8 27.0.0.0/8 31.0.0.0/8 36.0.0.0/8 37.0.0.0/8 39.0.0.0/8 41.0.0.0/8 42.0.0.0/8 49.0.0.0/8 50.0.0.0/8 58.0.0.0/8 59.0.0.0/8 60.0.0.0/8 69-79.0.0.0/8 82-95.0.0.0/8 96-126.0.0.0/8 127.0.0.0/8 197.0.0.0/8 221-223.0.0.0/8 224-239.0.0.0/8 240-255.0.0.0/8 Here is an updated list with some broader subnets: 0.0.0.0/7 2.0.0.0/8 5.0.0.0/8 7.0.0.0/8 14.0.0.0/8 23.0.0.0/8 27.0.0.0/8 31.0.0.0/8 36.0.0.0/7 39.0.0.0/8 41.0.0.0/8 42.0.0.0/8 58.0.0.0/7 60.0.0.0/8 69.0.0.0/7 71.0.0.0/5 82.0.0.0/3 114.0.0.0/5 122.0.0.0/6 127.0.0.0/8 -Ryan White
