This script first validates the format of the IP address using a regular expression. Then, it checks the IP address against several spam databases by constructing DNS queries. Finally, it prints whether the IP address is found in each database or not. Note that the DNSResolver
struct is a placeholder for performing actual DNS resolution, and in a real-world scenario, you would need to implement this functionality using a DNS resolver library or system call.
