Both IPs are Level3.com customers. I suspect that they are dial-up IP addresses.
Level3 does not publish suballocation information, so the most you could hope to do is a little detective work on your own. HOWEVER, be aware that some jurisdictions would consider such probes to be criminal acts. That said, if you want to take the chance, you can try to telnet to port 25 on each IP and see if they are running an MTA that will give away who they are, such as:
telnet 188.8.131.52 25
Or you can see if they have a web site at that IP via:
You can also complain to abuse at level3.com, but it won't get you anywhere.
Your best bet is to submit your logs to DShield.
BTW, what you are reporting is VERY common. It is not unusual to see a few hundred such probes per hour some days.
