C6300 Connectivity Issues (Mediacom)

Posting this to try to determine if I am actually receiving a DoS attack and if there's anymore troubleshooting I can do on my end waiting for my ISP to respond to a service call scheduled on October 9th. I have a 100Mbps line, but I'm only getting between 1-5 down and .5-1 MBps up at any given time.

 

I'm also receiving every 10 mintues exactly the following notification in Logs:

[DoS attack] ICMP Flood from fe80:0000:0000:0000:96d4:69ff:fe55:3019

 

I am just wondering if this is a false positive, I do not know much about IPV6 addresses but it says Local-Link when I try to resolve the IP. 

 

Firmware Version  V2.01.18
