From a honeypot log excerpt, which IP address is shown as performing a port scan?

• A. 194.222.156.169
• B. 212.244.97.121
• C. 172.16.1.107
• D. 24.9.255.53

Answer: (A)

Looking for a port scan in a honeypot log means spotting a single external source making quick, repeated connection attempts to many different ports on the honeypot. That burst of activity across numerous ports from one IP is the telltale sign of a scanner, not normal service access. The address 194.222.156.169 stands out because the log shows it initiating connections to a wide range of ports in rapid succession, which matches the behavior of a port scan. Other addresses either don’t show that broad, rapid probing pattern or are internal/private addresses that wouldn’t typically appear as external scanning sources. So, the IP 194.222.156.169 is identified as performing the port scan.
