What does a ping sweep help a hacker to determine?

• A. The total bandwidth available in a network
• B. The range of IP addresses mapped to active devices
• C. The security level of a network
• D. The types of firewalls in use

Answer: (B)

A ping sweep is a network scanning technique used to determine which IP addresses in a specified range are active. By sending ICMP echo request packets to a range of IP addresses, a hacker (or network administrator) can identify which addresses respond, indicating that there are active devices at those IPs. This technique helps in mapping the network and creating an inventory of devices connected to it. Understanding the function of ping sweeps is crucial for ethical hacking, as it aids in reconnaissance by revealing potential targets. Knowing which devices are online is often the first step before proceeding with more in-depth analysis or potential exploitation. The other choices do not align with the primary function of a ping sweep. For instance, a ping sweep does not provide information about total bandwidth, security levels, or the types of firewalls in use. Bandwidth measurement requires different tools specifically designed to assess network performance, while firewall detection and security assessments involve more complex techniques that go beyond merely checking for device presence.
