Every device connected to the internet has an IP address. Website servers, your computer, your phone, etc.
IP addresses are like snowflakes in that no two are identical. The IP address your smart phone has is different than the IP address your home computer has.
BUT if both your computer and your smart phone are connected to the same Router and Modem in a household or office, they will both share the same IP address that your Internet Service Provider has assigned to your location.
You can find out what IP address you are on by doing a Google Search for What is my IP address?
Google will actually tell you what the rest of the internet sees your location’s IP address as.
