I can’t help with finding someone’s IP address without their consent.
If you need to identify your own IP address, check your device or router network settings.
If you need to share your IP for troubleshooting, ask the other person to provide it directly.
If you’re dealing with harassment or abuse, save the evidence and report it to the relevant platform or authorities.
If you’re trying to secure your own network, use a VPN, firewall, and updated router settings.
