Invalid IP address

[Steven Lee <idsforensic () yahoo com>]

I am seeing this on my router syslog after I applied an access list on the 
internal interface. Can anyone tell me what this could be? The 68.84.8.41 
is a comcast IP that is active on the network; however, someone inside our 
network is attempting to use it to go out to other sites? Thanks for your 
help.
