The iPhone is a powerful, user-friendly device packed with features that many users barely scratch the surface of—including network-related tools. One such feature that often goes unnoticed is the ability to find your IP address directly from your iPhone. Whether you’re troubleshooting a connection, setting up a network device, or just curious, knowing how to locate your iPhone’s IP address is a useful and straightforward skill.
This article provides a comprehensive, step-by-step guide on how to find the IP address on your iPhone—both internal (local) and external (public). We’ll also explain what IP addresses are, why they matter, and how they function on your device.

1. What Is an IP Address?
An IP address (Internet Protocol address) is a unique string of numbers assigned to a device when it connects to a network. It functions like a home address for your device—allowing it to communicate with other devices on the internet or local network.
Example:
- IP addresses typically look like this: 192.168.1.10 (IPv4) or fe80::1c2b:74ff:fe4e:1a2b (IPv6).
Every internet-connected device—including your iPhone—has at least one IP address, and sometimes more than one.
2. Types of IP Addresses: Internal vs. External
There are two main types of IP addresses associated with your iPhone:
1. Internal IP Address (Local)
This is the address your iPhone uses within your Wi-Fi network. It’s assigned by your home router and used to communicate with other local devices, like printers or smart TVs.
2. External IP Address (Public)
This is the address your network uses on the internet. It’s assigned by your Internet Service Provider (ISP) and is usually shared among multiple devices in your home.
In most cases, when people refer to their IP address, they’re referring to the internal IP unless specified otherwise.
3. Why Would You Need to Know Your iPhone’s IP Address?
Here are some common reasons why you might want to find your iPhone’s IP address:
- 📡 Network troubleshooting
- 📲 Setting up smart home devices
- 🔧 Assigning static IPs for stability
- 🧠 Learning how networking works
- 🔒 Checking for unusual activity or network conflicts
- 🖥️ Allowing or blocking your iPhone in a firewall or router
No matter your reason, finding your IP address on iPhone is quick and easy.
4. How to Find Your Local IP Address on iPhone
This method works when your iPhone is connected to a Wi-Fi network.
Step-by-Step Guide:
- Open the Settings app on your iPhone.
- Tap on Wi-Fi.
- Find the Wi-Fi network you’re connected to (it will have a checkmark).
- Tap the small (i) icon next to the network name.
- Scroll down to the IPV4 Address section.
- You’ll see your IP Address listed—typically something like 192.168.x.x.
You can also find information like Subnet Mask, Router (gateway), and DNS server in this same section.
Note: If you’re not connected to Wi-Fi, this method won’t display a local IP address.
5. How to Check Your Public IP Address on iPhone
The public IP address is a little trickier to find directly through system settings, but it’s still accessible.
Methods:
- Connect your iPhone to Wi-Fi or cellular.
- Use any web-based IP checker service from Safari.
- The service will detect and display your public IP.
This is the IP visible to external websites and services. It’s often shared among all devices connected to the same router.
6. How IP Addresses Work on Wi-Fi vs. Cellular
Your iPhone behaves differently depending on how it connects to the internet.
When on Wi-Fi:
- Your iPhone receives a local IP address from your router.
- It shares the router’s public IP address with other devices in your home.
When on Cellular (4G/5G):
- Your iPhone gets an IP address directly from your mobile carrier.
- In most cases, this IP is dynamic and external.
- You can’t see this IP in the same way as with Wi-Fi settings.
Your public IP while on cellular can also change frequently, depending on the carrier’s network.
7. Understanding Dynamic vs. Static IP Addresses
Not all IP addresses are permanent. Let’s break it down:
Dynamic IP Address:
- Changes automatically from time to time
- Assigned by DHCP (Dynamic Host Configuration Protocol)
- Most home networks and cellular networks use dynamic IPs
- Easy, no manual setup required
Static IP Address:
- Manually configured and does not change
- Useful for advanced setups like port forwarding
- Can improve stability when needed for specific apps or devices
Your iPhone typically uses dynamic IP addresses, but some routers let you assign static IPs based on the device’s MAC address.
8. How to Change Your iPhone’s IP Address
You might want to change your IP to troubleshoot a problem or switch to a static address.
Change to a New Dynamic IP:
- Go to Settings > Wi-Fi
- Tap the (i) next to your network
- Tap Renew Lease at the bottom
This will force your router to assign a new IP (if available).
Set a Static IP Address:
- Open Settings > Wi-Fi > (i)
- Scroll to Configure IP
- Select Manual
- Enter the IP address, Subnet Mask, and Router info
Caution: Only do this if you know what settings to use; incorrect inputs can cause connection issues.
9. Troubleshooting Common IP Address Issues
If you’re having trouble connecting to the internet or apps aren’t working properly, the issue may be IP-related.
Common Fixes:
- Renew Lease (Wi-Fi > Info > Renew Lease)
- Forget the Network and reconnect
- Restart your router and iPhone
- Reset Network Settings:
Go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings
This will erase all Wi-Fi passwords and restore default network settings.
10. Final Thoughts and Best Practices
Learning how to find the IP address on your iPhone may seem like a minor technical detail, but it’s incredibly helpful—especially when troubleshooting, setting up smart devices, or understanding how your phone interacts with networks.
Quick Recap:
- 📱 Internal IP = Wi-Fi network address (Settings > Wi-Fi > (i))
- 🌐 External IP = Public address seen by websites (check via browser)
- 🔁 Use “Renew Lease” to get a new IP
- ⚙️ Configure a static IP only if needed
- 📶 Reset network settings if you’re facing connection issues
By understanding how IP addresses work on your iPhone, you’re better equipped to handle network issues, ensure security, and set up devices more effectively.
