There are privacy laws in the EU that could prevent you from doing this, because you can't publish personal information, pursuant to current and new rules (GDPR) effective in 6 weeks. This includes an IP address:
Personal data is any information relating to an individual, whether it
relates to his or her private, professional or public life. It can be
anything from a name, a photo, an email address, bank details, your
posts on social networking websites, your medical information, or your
computer's IP address. The EU Charter of Fundamental Rights says that
everyone has the right to personal data protection in all aspects of
life: at home, at work, whilst shopping, when receiving medical
treatment, at a police station or on the Internet.
Whether or not someone will come knocking on your door to arrest or sue you is hard to tell, but the odds are good that somebody else whose computer system you are using will care (because they do business with the EU), and they will make you stop.
