Just that IP? I would expect more IPs scanning your ports. I get about six
IPs scanning my IP every day.

If the scanner wants to identify anything, like an open port, they need to scan
using a real IP otherwise why scan.

If you are taking about a DOS (Denial of Service) then all of the IPs would be
faked as the person doing the DOS does not want to see any replies.

The odds are very good.

Almost all spam and port scans are done from a compromised computer. Some
dummy has clicked on a link to a greeting card and downloaded a trojan and now
someone else has control of the computer.
