What if it was with my IP Adress?

Folks can certainly believe the world is flat, too. Doesn't mean the world is flat...

Here, you can best learn how to improve your security. Two-factor authentication and trusted telephone numbers and related, for instance. Current software versions and updates, too. Unique passwords.

To become more aware of scams and scammers and the techniques they use. These scams are how folks get in trouble. Rather less often through vulnerabilities and security hacks. We are easier to hack than are our devices. We might get scammed, or we reuse a password, that sort of thing.

Maybe learn a little more about how IP networking works, too. The entire active IP (IPv4) address space is scanned by various folks —including those maliciously inclined—nearly continuously. If there were an iPhone security vulnerability solely requiring an IP address, its (mis)use would be, well, pandemic.

And for most of us, the firewalls that we’re connected through will block unexpected incoming network traffic.

PS: DHCP is an address coordination mechanism for IP (IPv4) networks, and not seemingly relevant here.

Very true, but:

I have to reset the router about once a month....

Needing to reset a router/firewall implies an issue with your ISP connection and/or modem and/or with your router/firewall, or potentially with malware running on your local network. Could be your ISP simply doesn’t have enough addressing capacity, or somebody else is explicitly configuring a conflicting IP address, too.

Blacklisted IPs arise when folks that were previously using that IP address were sending problematic traffic—whether that traffic was intentional, or due to misconfiguration, or malware—restart their router/firewall box. Same as you’re doing. The blacklisted IP address you’re referencing with your router/firewall is the source IP address for the connection and the source of the attack. For this discussion, the target IP address is the concern; that’s the iPhone address.

And the Ip address used on the Internet-outside the router/firewall is not the address associated with an iPhone or iPad or Mac on a Wi-Fi network, either.

But again, having an IP address of a host is not a security issue. It’s how IP works. This is not a security concern.

ps: Happy to discuss IP questions and networking questions over in the ‘cooler for the level-6+ folks, if there’s interest.

pps: There are three available private IP (IPv4) address blocks. In what’s called CODR notation, those three “private’” blocks are 192.168.0.0/16, 172.16.0.0/12, and 10.0.0.0/8. IPv6 has its own setup. I’m here also ignoring self-assigned IPv4 addresses, etc.

The local IP address is not viewable from outside (firewall).

You local address starts with 192.168.x.x

With some routers it may start with 10.0.x.x

And, just to clarify: your internet service provider provides the IP address depending on how your internet traffic is being routed through which of their servers. You can change that by resetting the modem/router - doing that reassigns it to another server. That is all. And, as far as I know, it has nothing to do with a phone since that is connecting to a cellular network through your cellular provider.

Further clarifications...

The ISP doesn’t coordinate the local IP address for a device on a residential or business (IPv4) network.

That’s all “behind” the router/firewall.

And handled by DHCP, for IPv4 networks.

And irrelevant to security.

And rebooting the router/firewall to (try to) change the assigned Ip address doesn’t change that the router/firewall blocks incoming traffic.

Again, any IP address collisions and DHCP services and the assigned IP address are not likely a factor in whatever is going on here.

But all this is just probably reading as confusing gibberish, and likely unhelpful to the original poster and their security concerns.

DHCP is unrelated to the reported/claimed security and to unauthorized access to an unlocked iPhone.

Every single host on an IP network has associated IP addresses.

That’s how IP networking works.

Having an IP address implies nothing about security, nor about authorized or unauthorized access.

That's the WAN address from your Internet provider and has nothing to do with you local DHCP assigned IP address.

The local IP address is not viewable from outside (firewall).

You local address starts with 192.168.x.x

You can tell us WHY exactly do you believe that your iPhone has been hacked? Provide details and we can help you better. Thanks.

Rebooting helps in many cases.

Are you Getting a Conflicting Error?:

Conflicting would be the Issue.

Use DHCP:

If you have DHCP (dynamic) (automatically assigned) enabled and are not using a static IP address (manually assigned), then the device’s IP address will independently change.

Point Being:

If someone used your IP Address, then things would conflict, and would not work, you’d be getting a message about this confliction-Error.

And, just to clarify: your internet service provider provides the IP address depending on how your internet traffic is being routed through which of their servers. You can change that by resetting the modem/router - doing that reassigns it to another server. That is all. And, as far as I know, it has nothing to do with a phone since that is connecting to a cellular network through your cellular provider.

“If someone used my IP address from my router how would i know? I mean besides they told me. How do i use a DHCP? I am not getting any type of “conflicting error” what do you mean by that?”

How to Know: Log in to your Router using the Default Gateway (192.168.0.1 or 192.168.1.1). So, enter either IP Address into the address bar of your Web browser. Then log in to your router. See what is signed into your network. Contact the manufacture and request the User Manual, if you do not have a hard copy of it.

DHCP (Dynamic Host Control Protocol) assigns the IP address automatically to the host (computer, printer, etc.)

Conflicting would say that your device’s IP Address is being used by something(s) else. So, Data would not transfer for the item.

Contact a Third Party Service, for more on setting this up.

We’re a little off topic here, but what resetting the router does is restart the DHCP daemon. On many routers (especially older ones) DHCP “breaks” and stops assigning IP addresses after a period time (weeks, usually). Another example of “when in doubt, reboot.” The reason it happens with many brands of routers is they mostly use the same public domain router OS kernel. It should not happen with newer routers from better-known manufacturers.

The way to see if this is the problem when you lose connection is to go to Settings/Wi-Fi, wait 30 seconds after connecting to the router, then tap on the i next to the network name. If the IP address begins 169.254.x.x that means that the router did not assign an address when the phone requested one, so the phone generated its own to create a local “ad hoc” network.

Thanks, but I know what caused your confusion; what was mis-read and then confused you.

Very true, but:

I have to reset the router about once a month (or two at the most): our internet connection will simply go "poof" (disappear). We have CenturyLink ADSL and are told to reset the router when that happens. And, when I do, it simply works again. And the IP address is different..

I've also had to reset it once for apparently having wound up with a blacklisted IP address: various emails to Europe would be returned as being from a "known" spam sending IP address. Centurylink advised that resetting it will result in a different IP address. I made a note of the "spam" IP address and, after resetting it, we had a different one and have been able to send emails to Europe.

This is the current one:

I just had to reset it about 3 days ago (no internet connection) and it was 97.120.106.199 before the reset.

Yes, I know about the local address - that is how I get on the modem's website. So I guess the iPv4 IP address is the one that was blocked and gets reset - I must say I did not know that part.
