I just checked my firewall log and in the past 5 hours, I had 6 port scans and active responses from the same IP address 34.168.1.34. I checked on WHOIS and e-mailed the dnsabuse address asking for the reason, an (obviously) automated response came firing back immediately saying that it did not come from them and must have been spoofed.
Is there anyway of proving or disproving this at all? The log also recorded the MAC addresses if this would help.
