A security analyst is writing a shell script to identify IP addresses from the same country. Which of the following functions would help the analyst achieve the objective?
A.
function w() { info=$(ping -c 1 $1 | awk -F “/” ‘END{print $1}’) && echo “$1 | $info” }
B.
function x() { info=$(geoiplookup $1) && echo “$1 | $info” }
C. While geographic information (provided by geoiplookup) can help determine the region of an IP address, it does not provide specific information about organizational ownership. The primary goal here is to identify network addresses that belong to the same company, which is more accurately achieved through ASN information.
Thus, despite the comments suggesting otherwise, Option C remains the best choice because it provides ASN information, which is essential for grouping IP addresses by the organization that owns them.
Correct Choice
C. function y() { dig $(dig -x $1 | grep PTR | tail -n 1 | awk -F ”.in-addr” ’{print $1}’).origin.asn.cymru.com TXT +short }
This function directly achieves the goal of identifying network addresses belonging to the same company by using ASN information.
I think chatGPT confused the question, after asking again:
Based on the objective to identify IP addresses from the same country, the most appropriate function is:
B. function x() { info=$(geoiplookup $1) && echo “$1 | $info” }
This function directly uses geoiplookup to provide geographic location information, including the country of the IP address, which is essential for identifying if IP addresses are from the same country.
This function takes an IP address as an argument and uses the geoiplookup command to get the geographic location information associated with the IP address, such as the country name, country code, region, city, or latitude and longitude. The function then prints the IP address and the geographic location information, which can help identify any IP addresses that belong to the same country.
