While it’s possible and, unfortunately, regularly shown how to proxy
I2P addresses without affecting clearnet traffic, such configuration
brings no
anonymity whatsoever . Unless you don’t mind browsing the I2P network

fallback proxy (keep on reading to learn how to do just that). If you’re following this guide on a browser other than the Tor
Browser, remember to configure your browser to proxy DNS requests.
