strange activity

NAV2008

Vista OS

 

Ok it seems again that in my activity log, I'm getting another "port blocking allowed"  this time this is the IP address

 

66.139.198.255(3).

 

Now this address falls in the range of the IP addresses of my ISP

And this IP address is very similar to mine

 

It shows up when I turn my computer on or reboot and then periodically. I do get the Port Blocking allowed 192.168.0.1(8). and that entry is much more frequent, but the 66.139.198.255(3). still shows up randomly

 

The last time I noted this (last week) the IP address (66.142.168.255) was different than the one above, but again similar to the IP address I had at the time

 

In both instances they end in.255 and seem to come over port 3

 

I have contacted my ISP but they are slow to respond

This appear to be someone hacking me?

Or someone using my connection?

 

I see no connections in the connection log that coincide with the activity time

Or is this some legit  connection from my ISP?

It's interesting how in both cases they end in .255(3)

 

I have my trust local networks turned off. When I have trust local networks turned on I don't see these in my activity log

 

this is just very concerning
