What methods can I use to capture network traffic at the IP address level with pcapp?

You can use two main methods for capturing network traffic at the IP address level with pcapp:

1. Using the PCAP_OPEN_LIVE function: This function allows you to capture traffic from a specific network interface. You can specify the IP address of the interface you want to capture traffic from as an argument to this function.
2. Using the PCAP_OPEN_OFFLINE function: This method allows you to capture traffic from a file. You can specify the file path of the capture file as an argument to this function.

How do I filter and manipulate network traffic based on IP addresses using pcapp?

To filter and manipulate network traffic based on IP addresses using pcapp, you can use the PCAP_FILTER function. You can pass a filter expression as an argument to this function. Here are some examples of filter expressions that you can use:

• To capture traffic from a specific IP address, you can use the following filter expression: "ip src 192.168.1.1"
• To capture traffic to a specific IP address, you can use the following filter expression: "ip dst 192.168.1.1"

You can also use pcapp to manipulate network traffic based on IP addresses. For example, you can use the PCAP_SET_SNAPLEN function to set the capture length for each packet by IP addresses.

Is it possible to obtain IP addresses of devices connected to a network using pcapp?

Yes, it is possible to obtain IP addresses of devices connected to a network using pcapp. You can use the PCAP_LIST_INTERFACES function to get a list of all network interfaces on your system. Then, you can use the PCAP_OPEN_LIVE function to capture traffic from a specific network interface. Once you have captured the traffic, you can use pcapp to extract the IP addresses of the devices that sent the traffic.
