What information can be obtained from the IP address?

A person who knows your IP address knows your location (including region, city, zip code and even street). Marketing specialists use these results together with other information obtained from metadata, cookies, trackers, etc. to create a detailed profile of your person. They can obtain knowledge not only about your location, but also about the websites you visit, your interests, search terms, etc. This allows you to display, among others, profiled ads or personalized search results.
Internet providers have access to even more information - your personal data and have the ability to track the information you send and receive (which is not encrypted) and share this data with governmental organizations.

That is why it is often worth taking care of your privacy and hiding your IP address using, for example, VPN services. see more.

Notes on geolocation

The location of the IP address, ie the location of the computer is usually inaccurate . While in the case of large cities it can be assumed that the indications are most likely correct, in the case of other locations it may lead to very large discrepancies.

Often the location may point not to the address of the target computer but to the address of the internet provider (e.g. in the case of cellular networks)

Types of addresses - static and dynamic

IP addresses can be assigned statically or dynamically. Static IP addresses are always assigned to the same device and are usually reserved for the e-mail server / business server. These IP addresses are assigned from a pool of available addresses from your ISP. A static IP address usually costs extra.
A dynamic address means that your IP will change, e.g. every time you connect to the Internet, your IP will be different! These addresses are assigned randomly from the pool of the internet provider and are often assigned to individual clients, e.g. in the case of mobile telephony.

Ports - many computers and the same IP address

The IPv4 address pool is limited so it is not possible for every device to have its own unique IP address. Usually it is the other way around, i.e. many devices use the same IP address. For example, if you have a fixed-line Internet at home and a wireless network, all devices connected to this Wifi will have one, the same , shared IP address on the Internet.
This is possible thanks to ports - the additional information that is sent with the IP that helps the router segregate traffic to a specific device or service on the subnet. Thus, having the sender's IP address alone, but without the port number, will often not allow you to accurately locate the device that sent the information, but only indicate a possible group of devices.
It is illustrated by the diagram below, in which different devices have the same IP -
