Network Analyzer: constant flow of ICMP packets to {myip}.ssh

Posted on November 8, 2015

I’m getting a constant flow (about 1 packet per second) of these ICMP network packets (See below). Can anyone enlighten me as to what is happening? My droplet is 104.236.22.84 and the address (52.19.78.160) changes in almost every packet. Thanks in advance.

#tcpdump -nv icmp
