Replaced the list comprehension `[ip_class(base_int + i) for i in range(total_ips)]` with a generator expression `(ip_class(base_int + i) for i in range(total_ips))` in `testping1.py`. When scanning large network ranges, eager evaluation with a list comprehension causes an O(N) memory spike by allocating the entire list of intermediate `ipaddress` objects into memory before passing them to the ThreadPoolExecutor. Using a generator expression lazily evaluates the IPs and drastically reduces the intermediate memory allocation to O(1) while providing a slight speedup from avoiding list overhead.

💡 What: Replaced an eager list comprehension with a lazy generator expression when creating the list of IPs to scan.
🎯 Why: Eager evaluation creates an unnecessary O(N) memory spike before the actual concurrent pinging begins, which is inefficient for large network ranges (like a /16 subnet).
📊 Impact: Reduces peak memory allocation overhead for intermediate sequences from O(N) to O(1) and provides a slight performance speedup.
