Unethical? Well, using those IP addresses, I would assume that this is an unroutable segment of your network (perhaps a private or management segment) rather than a public address. Using scanning tools such as have been mentioned on the public internet is probably unethical and might get your connection blocked by your service provider too. The tools can be used to look for weaknesses on the public internet so everyone is very wary of them and providers are quite hot on keeping their customers clean else other providers may block them out too.
Probing your own devices to see what ports are open, filtered or closed seems a valid thing to do, but don't go mad on it.
Kind regards,
Robin
