What exactly is an IP address?

Recently I've been interested in the Internet, etc. What is an IP address exactly and how can you locate it does each device have a different IP address, eg my laptop and mobile phone both connected to the Wi-Fi at different locations. Can you locate both?

It's best to take a look at Wikipedia is the best source for information online.
https://de.wikipedia.org/...IP-Adresse

Unfortunately it is not the best source at all.

Okay for what reason?
It has a lot of information about every topic and every information that is entered there has been checked to see whether it is correct. You can state Wikipedia as a source for every project for every study and is trustworthy.

Your router is between your local IP and the Internet

he usually gets a new ip from the provider every day and you use it on the internet. Your locale IP does not work on the internet.

With your mobile via WLAN, it's the same, with your mobile via 4G LTE etc you also have an IP that changes regularly, but you can't really locate it, at most the place where the signal really goes into the network and can be far far wech.

An IP address indicates the (physical) location of a device.
The IP address can change, which is usually not permanently assigned to a device, although that is also possible.

Well, to understand that you have to understand what a router is. Your router that you have at home connects two networks, your home network and the internet as a whole. Your router communicates with the devices in the internet and with the devices in your local network, so it acts as a kind of intermediary.
You can't (normally) directly access the devices in the home network from the internet, only the router.

So your router at home gets an IP from your ISP (internet provider). In addition, the devices in your home network also have IP addresses (these are assigned by your router itself). The IP addresses in the home network are only valid in the home network, and those in the internet are only valid in the internet. These are completely independent address ranges.

Now to the question of the location.
The fact that you can locate it is because you are logically not directly connected to every server there's. This means that if you are based in Hamburg Brahmfeld and visit a website in the USA, then the parcels probably have to first go to New York, then London, then Frankfurt, then to a central data center in Hamburg, and then to your home.
during the process, one then knows that you are, probably, in hamburg.

Makes sense?

Ok, that all sounds mega confusing so I wanted to locate an ip address, unfortunately the police can't do that because the person has deleted himself from the dating site and I wanted to ask if that's true?

For example, my cell phone and my laptop are connected to the wireless network. And what if you just turn off your cell phone can you still be located?

IP stands for Internet Protocol. The Internet Protocol ensures that data packets can be exchanged between sender and recipient via the Internet. Just like you have to write a sender and a recipient address on a letter, an IP packet must also contain a sender IP address and a recipient IP address. Every device that should be accessible on the Internet therefore needs a unique IP address.

how can you locate each device has a different ip address, for example my laptop and cell phone, both connected to the Wi-Fi at different locations.

You can't locate anything there. You get the IP address that you use from your access provider "borrowed". Based on the IP address, I can determine which provider you booked your internet access with. An IP address is also assigned to an Internet dial-up node. There are databases that I can use to roughly determine the region the entry node is in. A more precise location is not possible.

If you are now logged into the WLAN of a fast food restaurant with your mobile phone, you can be seen on the Internet with an IP address of the fast food restaurant or its provider.

No, they don't have the same IP addresses. Several devices in the same network can't have the same IP (well, they can, but then nothing works anymore).

If you have the IP of the router, it can always be traced back somewhat. But, as I said, not exactly.

There are 2, and sometimes more, levels of addresses. In your local network all devices have their own addresses, on the internet your whole home only has one (if at all, DS-Lite is often used, then you don't even have a real IP address).

You misunderstood something, or you're running a yodel diploma. Definitely a course with 3 names, where you can immediately see that it is not a real course. You are welcome to consult Wikipedia to use source information there, but:

someone described it well

Wikipedia is a platform on which everyone can write. Of course, the mass of committed people ensures that a lot is often right. But for a source reference you need an author or editor to whom the quoted content can be assigned and who is then still worthy of citation (e.g. An expert). And that is completely absent from Wikipedia, which is why it is not suitable as a source.

Wikipedia is not a Tested Truth. They are neither experts nor anything else, and they interpret it as they want, the admins in particular are very unapologetic and consider their interpretation to be much more correct.

As I said, nobody likes to bother in a small retraining and you take what is right there without taking the sources of the article. But when you are studying, you only think that you have not understood the study.

Oh, understand on the day when the acc was deleted, the data disappear then it is no longer possible. You are also not obliged to save the data for that long?

That would be illegal, we do not yet live in such a surveillance state.

Krass, and how do they find such verbecher? I mean they delete the acc too. Well that all sounds meag interesting in usa everyone knows about everyone

Nope not even there. It depends on the terms and conditions. And why should I save an extra IP that always changes anyway lol. Doesn't bring me anything. Sufficient if I save the user who is logged in and his behavior, the IP brings me nothing (data garbage). According to the motto: I would like to know the customer's buying behavior, which IP he takes is irrelevant to me. Users and IPS will not be able to sell, so no one will buy it and no one will save it.

Outside (on the Internet) they have the same IP address - that of the router
