ou've been tasked with doing a network vulnerability assessment. A list of over $5000$ IP addresses has been provided in the form of a file. This list contains a mixture of valid IP addresses, incorrectly formatted IP addresses, IPv$6$ addresses, shorthand IPv$6$ notations, and even some containing evasive gibberish data.

Your task is to identify and flag malicious IP addresses that fall into one of the two categories listed below:

$1.$ IPv$4$ addresses starting with $"92\mathrm{.}85."-$ These have been identified as IPs of threat actors.

$2.$ IPv$6$ addresses that match the pattern $"2510$:a$5$:$*$:$*$:$*"-$ These have been identified as IPs of C$2$ servers.

After the identification of these IP addresses, your next task is to capture the last character of each IP address in the exact order in which they occur in the file. Use these characters to construct the Flag. example format: HQ$8\{$IP$\_$characters$\}.$

Note: Must include the script developed to solve this quest in the report.
