how do i get a new IP address for my iPhone/devices if my ISP isn’t helping me do so?!

It is normal for a device to have the same IP address for long periods of time. If you are connected to Wi-Fi your phone’s IP address is a local network address, and will never change; depending on the router most likely it will be 192.168.something.something or 10.0.something.something. The IP address your router displays to the Internet will also rarely change; you can find out what it is by going to https://whatismyipaddress.com (Ignore the ad on this site for a service you don’t need).

The IP address for a cellular connection is determined by your carrier, and will vary as you move around. But if you stay in the same service area it most likely won’t change either.

Why do you want your IP address to change? Do you regularly change your house number on your street?

Your IP address is not a security risk; having the same IP address does not make any other security steps “null and void”; I have no idea where you saw such cockamamie nonsense. Changing your IP address is neither necessary nor sufficient for securing your devices. Even if you could change it, the first time you connected to anything your IP address would be known around the world, unless you could change it every time you went online. But then no websites or apps would work, because when they respond to you they connect to your IP address. Think about it for a moment: Apple.com has had the same IP address for 40 years; does it have weak security? So does the White House. How is it’s security? And how about https://www.nsa.gov; do you think they are insecure?

However, if you have inexpensive Internet of Things devices such as security cameras they certainly are security risks. And so is your router if it’s firmware is not up to date or if the router is more than 5 years old. A VPN connection will change your IP address, but it will also put you at risk because not all VPN providers are honest; actually, most are not, so that is not a good solution either.

There are ways to manually change your IP address, but seeing as you willingly admit that you are not tech savvy, I would not advise trying to do something like that. While changing your IP address is one way to help cybersecurity, the biggest things you can do are

1. Not reuse passwords
2. Change passwords frequently (about every 60 days)
3. Do not give websites your personal information (including e-mail addresses) unless you know and trust the company

Altogether pretty common sense stuff, but can make a world of a difference. Using a VPN (if legal in your area) is also another way to keep your traffic secure, but make sure you aren't using some free thing off the internet that you found, as that could pose a risk as well. The key is doing the research and keeping up with your security.

Changing your IP address doesn’t help. Bots simply try all ip addresses looking for iot devices that don’t have good security. You need to secure your devices, not think that changing your IP address will protect you. It won’t.
