- Is it i2p ip address (how can confirm)
It is probably not I2P’s IP address, I2P is an in-network darknet primarily with “outproxies” operated on a voluntary basis. We do not operate as a transparent proxy or VPN unless expressly configured to do so. Within I2P you have a cryptographic address only, and outside I2P you’ll have the shared address of the outproxy. You can find the address of your outproxy by running the following command(Please correct me if there’s a better, more whonix-ish way to do this)
https_proxy=http://127.0.0.1:4444 http_proxy=http://127.0.0.1:4444 curl https://ifconfig.me
Running that command should result in the outproxy address being shown. I2P is not unlike Tor in this way, it’s necessary to configure applications so that they work with I2P.
- But my linux machine ip not changed new ip after used sudo service i2pd start in whonix machine.
In the context of I2P(and indeed most things) this is perfectly normal. I2P(And Tor, and VPN’s) don’t change your network location. The only way to actually change your network location is to move your machine to a different network. Instead, they make it hard for other people on the network to determine your network location by obfuscating the information necessary to discover where you are. You appear to others as if you are in a hidden location, but your computer is still attached to the same ISP that it was before you installed I2P.
