Hi, I am detecting an increased amount of ICMP Ping traffic. The strange thing is that there are several sources that are hitting us about 1000 times a week. All of these sources have a last octet of some form of 36 and 37. 63.163.102.36 & 37 216.34.77.36 & 37 64.209.232.36 & 37 61.213.167.236 & 237 193.95.144.136 & 137 These are from different ISPs and in a couple countries. The destination is on a Cable Modem that has no inbound access. It's not causing an issue, it's just anomalous. Anyone else seeing this kind of traffic, or have any ideas on the origin?
