Where to find your IP address on iPhone
Your iPhone's IP address is in Settings under Wi-Fi. Open Settings, tap Wi-Fi, find the network you're connected to, tap the information icon next to it, and look for "IP Address" in the list. That's the address your phone uses on your home or office network. If you're on cellular data instead, the IP address appears under Settings > Cellular > Cellular Data Options > Mobile Data Network, though most people don't need this one.
The address you see will look like four numbers separated by dots — something like 192.168.1.45. This is your local IP address, the one your router assigns to your phone so other devices on your network can find it. It's different from your public IP address, which is what websites see when you browse. For most security purposes, you only need the local one.
If you're not currently connected to Wi-Fi, you won't see an IP address in that menu. Connect to your network first, then check Settings again. The address may change each time you reconnect, depending on how your router is set up.
Key Takeaways
- Your iPhone's local IP address is in Settings > Wi-Fi, next to the network name you're connected to.
- The address looks like four numbers with dots (192.168.1.45) and lets other devices on your network find your phone.
- You need to be connected to Wi-Fi to see the address — it won't appear if you're only on cellular data.
- This local address may change when you reconnect to the network, so don't rely on it staying the same.
Why you might need to know your IP address
Knowing your IP address is useful when you're troubleshooting network problems or setting up a device that needs to connect directly to your phone. If someone asks you to check your network settings or a tech support person needs to see what address your phone has, you now know where to find it. It's also helpful if you're trying to figure out whether your phone is actually on your network or if something is blocking the connection.
You might also need it if you're setting up a printer, security camera, or other device that requires you to enter an IP address to connect. Knowing your phone's address helps you understand whether devices are on the same network and can communicate with each other.
The difference between local and public IP addresses
Your local IP address (the one in Settings) only works on your home or office network. It's assigned by your router and lets devices near you find your phone. Your public IP address is different — it's what your internet provider assigns to your entire network, and it's what websites see when you browse. You don't need to find your public IP address in Settings because it's managed by your internet provider, not your phone.
If you're curious about your public IP address, you can find it by opening a web browser on your iPhone and searching "what is my IP address." The search results will show your public one. But for most security and troubleshooting work, the local address in Settings is what matters.
What to do if the IP address keeps changing
Your iPhone's IP address may change each time you reconnect to Wi-Fi or restart your phone. This is normal and happens because your router assigns addresses automatically. If you need your phone to have the same address every time, you can set a static IP address, but this requires going into your router's settings, not your iPhone's settings.
Most people don't need a static IP. If a device needs to find your phone reliably, it's usually easier to use your phone's name (which stays the same) rather than its IP address. But if you do need the address to stay put, log into your router's admin panel and look for "DHCP reservation" or "static IP" options. The exact steps depend on your router model.
Checking your IP address on cellular data
If you're using cellular data instead of Wi-Fi, your IP address works differently. You can find it in Settings > Cellular > Cellular Data Options > Mobile Data Network, but most people never need to check it. Your cellular IP address is assigned by your phone company and changes frequently. It's also not useful for connecting to devices on your home network, since cellular data doesn't connect you to your home network at all.
If you need to connect to a device at home while you're away, you'll need to be on Wi-Fi, not cellular. Cellular data connects you to the internet through your phone company's network, not your home network, so your home devices won't be able to reach you.
Using your IP address safely
Your local IP address is safe to share with people who need to help you troubleshoot your network. It only works on your home or office network, so someone outside that network can't use it to reach your phone. However, don't share your public IP address (the one from a web search) with people you don't trust, since it can reveal your general location and internet provider.
If you're concerned about network security, focus on keeping your Wi-Fi password strong and your iPhone's software up to date. The IP address itself is less important than controlling who can connect to your network in the first place.
Frequently Asked Questions
Can I change my iPhone's IP address?
You can't change it directly on your iPhone, but you can force it to get a new one by turning Wi-Fi off and back on, or by disconnecting and reconnecting to the network. If you need a specific IP address, you'll need to set up a static IP in your router's settings, not on your phone.
Why does my IP address show as 169.x.x.x?
That means your phone isn't getting an address from your router. Restart your phone, forget the Wi-Fi network in Settings, and reconnect to it. If it still shows that number, restart your router. If the problem continues, your router may not be assigning addresses correctly.
Is my IP address the same as my phone's name on the network?
No. Your phone's name (like "James's iPhone") is separate from its IP address. The name stays the same, but the IP address can change. Both help identify your phone on the network, but they work differently.
Do I need to know my IP address to use my iPhone normally?
No. Your phone handles IP addresses automatically. You only need to know it if you're troubleshooting a network problem or setting up a device that requires it.
