and you also forgot the window titles. but it doesn't matter anyways. all IP addresses are by definition public; there are only about 4 billion of them anyways

and you also forgot the window titles. but it doesn't matter anyways. all IP addresses are by definition public; there are only about 4 billion of them anyways, less than there are people on Earth. you should probably focus more on making your code secure rather than obfuscating your IP address in screenshots. for example, in addition to what has already been said about /tmp, system() is almost never the correct answer. in this case, if options.user or dns contain "special characters" they may be interpreted by the shell differently from what you intended.
