An IP address is a unique identifier for each device. When you ask, "what is my ip", you're inquiring about this unique identifier. Any two devices can receive or transfer information only after they both identified each other with an IP address. This address is sensitive information and requires protection. It can be simply changed with services such as VeePN or other private networks. A VPN will change your IP address by placing you in a different country virtually. Your traffic and personal data is safe and routed through a tunnel with 256-bit encryption, so that no one can see where you are and what you are doing online.
