Strange ping reply packets

[Artur.Nowak-sec-incidents () WODIP OPOLE PL (Artur Nowak)]

Hi all,

today I have two strange floods of pnig reply packets. I am not sure if
it's a smurf attack or something. It looks the source ip addresses are
random generated so I don't know if it's possible to find real source of
attack.
If anybody have some ideas how to find source address I will be grateful
for help.

BTW: What is usually listening on port 6700/tcp?
Feb  8 10:19:56 TCP: port 6700 connection attempt from 208.184.216.206:1526

PS. Sorry for a bit long logs.
