Does Using The Internet Through Your Mobile Data Produce An Ip Address

Does the IP address belong to the SIM card or to the mobile IMEI number?

Our 3G and 4G Fixed IP SIM Cards give you a connection to the mobile Internet with a public IP address enabling you to connect directly to your 3G or 4G router from anywhere in the world and use port forwarding to connect to your devices connected to your router.Your phone is provided with an IP address depending on the network you are connected to. The router you are connected to provides the IP address.If you are connected to a network that allows it, you can set up a static IP address that would never change, but it would only work on that one specific network. Additionally, your outside IP address is most likely different than the IP address that you see in your phone.

Do mobile phones have IP addresses?

Any device in an IP (Internet Protocol) based network has an IP address.This is independent from the nature of the device, it could be a supercomputer or some microchip in a talking doll.So from the perspective of a server to whom your phone is connected, you do have an IP address, otherwise it would not know where to send the data.However from the point of view of your phone, you might not. Usually the IP address is a tunnel address which is managed by your mobile service provider. They are in charge of knowing in which cell your phone is currently in and forwarding the packets to and from your cellphone.There is a nice if terse and very technical presentation online that outlines how cellphone addressing works:https://meetings.ripe.net/ripe-5...

How accurate can we track location using an IP address?

Not very.IP has no provision for location information. A fixed connection IP such as a residential or business wired internet service can usually be narrowed down fairly closely, especially if that address engages in a lot of e-commerce, but those lookup databases can be wildly inaccurate or simply out of date. Residential service IPs can change daily among that ISP’s customers, so it’s hard to pinpoint those beyond city level. (I once had an IP address that was listed in the major databases as being in 6 different states and two separate countries)And sometimes, if they can’t pin it down closer than the country level, they’ll pick a set of coordinates roughly in the geographic center. This turned out very badly for one family in Potwin, Kansas, whose farm was the default for any US-based IP that couldn’t be narrowed down any closer. After the database operators became aware of the problem, the default coordinates were changed to a spot in the middle of Cheney Lake, a reservoir near Wichita, Kansas.If the IP address belongs to a mobile network operator, then all bets are off, as those addresses could pop up almost anywhere.And then the person could be using a VPN. I use a VPN that hops onto the internet via an address that the IP geolocation databases have listed as being in Saskatchewan, Canada (when in fact, the datacenter is actually just outside Montreal).The databases are put together from a variety of sources, but one of the most common methods is that the operators will buy bulk and anonymized data from e-commerce sites that ship physical goods, who log the IP address of every transaction (for fraud prevention purposes). They can then generate a list of addresses they shipped/billed, and correlate to an IP address, especially if there are frequent purchases from the same IP/physical address pairs. There are other data sources as well to refine the accuracy.

How do IP addresses work? Does the IP address vary from computer to computer, or does it depend on the internet connection you're using? If I use my neighbour's Wi-Fi from my computer, does that change my IP address?

If you connect to a router, the router has one IP address and it allocates other local addresses to the devices connected to it to recognize them. But all the devices connected to that router have a common IP. The local address is just for the router to easily identify which device asked for which website.For eg: You have your mobile and laptop connected to the router.Say your router has an IP of 10.10.10.10and the router has assigned local ip of 192.168.0.100 - Mobile.192.168.0.101 - Laptop.If you go to http://www.whatismyipaddress.com from both the devices you'll see 10.10.10.10 and not 192.168.0.100 or 192.168.0.101 because local ip addresses are not used anywhere outside your network.So what happens when you go to a website? Well, say you entered:http://google.com in mobileandhttp://quora.com in laptop.Your router will then send a request for google and quora by the address of 10.10.10.10. The webservers of google and quora will then get a message that 10.10.10.10 wants your webpage and as a server usually does, it'll respond and give it to the router which asked for it (i.e. your router).Your router now has google and quora's webpage. It'll then see which local ip address asked for which website. Router maintains a table which keeps track of the MAC address and local IP address assigned to them. It then realizes your mobile asked for google and laptop asked for quora and will deliver it to them.How ever if you have 2 different LAN connections of 2 different ISP (Internet Service Providers) going in 2 different laptops they'll have 2 different IP addresses. But when you use a router, it performs what we call as NATing or (Network Address Translation).
