How to Find Your iPhone's IP Address (Wi-Fi and Cellular)

Your iPhone has more than one IP address — and which one matters depends entirely on what you're trying to do. Whether you're troubleshooting a network issue, setting up a home server, configuring a printer, or just satisfying curiosity, knowing where to look (and what you're actually looking at) makes the difference between a quick fix and a frustrating rabbit hole.

What Is an IP Address on an iPhone?

An IP address (Internet Protocol address) is a numerical label assigned to your device so it can communicate on a network. Think of it like a street address — without it, data packets wouldn't know where to go or come back from.

Your iPhone can have two types simultaneously:

• Private IP address — assigned by your router, visible only within your local network (home Wi-Fi, office network, etc.)
• Public IP address — assigned by your ISP, shared across all devices on your network, and visible to the wider internet

Most troubleshooting tasks — like configuring port forwarding, setting a static IP, or connecting devices on the same network — require your private IP. Tasks involving firewalls, VPNs, or external access typically involve your public IP.

How to Find Your iPhone's Wi-Fi IP Address 📱

This is the most commonly needed address, and iOS puts it just a few taps away.

1. Open Settings
2. Tap Wi-Fi
3. Tap the ⓘ info icon next to your connected network name
4. Scroll to the IPv4 Address section
5. Your IP address appears under IP Address

You'll typically see something like 192.168.1.x or 10.0.0.x — both are standard private IP ranges defined by RFC 1918. This address is assigned dynamically by your router via DHCP (Dynamic Host Configuration Protocol), which means it can change when you reconnect or when your router's lease expires.

IPv4 vs. IPv6 — What's the Difference?

On the same screen, you may also see an IPv6 address — a longer string using both numbers and letters, like 2001:0db8:85a3::8a2e:0370:7334. IPv6 is the newer standard designed to solve IPv4 address exhaustion. Most home networks use IPv4 internally; IPv6 is more commonly assigned at the ISP level. For most local network tasks, IPv4 is the one you need.

How to Find Your iPhone's Cellular IP Address

When connected to cellular data rather than Wi-Fi, your iPhone is assigned an IP address by your carrier. This is harder to surface natively in iOS.

Option 1: Use a browser-based IP lookup Visit any IP lookup site (search "what is my IP") in Safari while on cellular data (Wi-Fi turned off). The address shown is your current public-facing IP — which, on cellular networks, is often carrier-grade NAT (CGNAT), meaning it's shared among many users and not truly unique to your device.

Option 2: Check via Settings (limited) Go to Settings → General → VPN & Device Management or Settings → Cellular — iOS doesn't display the raw cellular IP here by default, so a browser-based check remains the most reliable method.

How to Check Your Public IP Address 🌐

Your public IP is the address the internet sees, regardless of whether you're on Wi-Fi or cellular. It's assigned by your ISP (Internet Service Provider) or carrier.

To find it:

• Make sure you're connected to the network you want to check
• Open Safari and search "what is my IP address"
• Google and most search engines display it directly in the results

Keep in mind: if you're using a VPN, the IP shown will belong to the VPN server, not your actual ISP-assigned address. That's intentional — masking your real IP is one of VPN's core functions.

Setting a Static IP on iPhone (When It Matters)

By default, your router assigns a dynamic IP that may change. For some setups — like always reaching your iPhone at the same address for network automation, home lab configs, or printer sharing — a static (manual) IP is more reliable.

To set a manual IP on iPhone:

1. Go to Settings → Wi-Fi
2. Tap ⓘ next to your network
3. Under IPv4 Address, tap Configure IP
4. Select Manual
5. Enter your desired IP, subnet mask (255.255.255.0 is standard for most home networks), and router address

Alternatively, you can assign a DHCP reservation directly through your router's admin interface — this lets the router always hand the same IP to your iPhone based on its MAC address, without touching iPhone settings at all.

Factors That Affect Which IP Address You See

Not every iPhone user will see the same type of address or need the same information. Several variables shape your situation:

Why Your IP Address Might Keep Changing

If you've noticed your iPhone's IP shifting between sessions, DHCP lease renewal is almost always the reason. Routers lease IPs for a set period (often 24 hours to a week). When the lease expires or you reconnect, the router may assign a different address from its available pool.

This is normal and by design — it helps routers manage address pools efficiently. It only becomes a problem when your workflow depends on reaching your iPhone at a consistent address, which is when a static assignment (via manual settings or DHCP reservation) becomes worth considering.

The Variable That Changes Everything

Finding your iPhone's IP address is mechanically straightforward. What makes the answer more nuanced is which IP address matters for your specific task — private or public, IPv4 or IPv6, dynamic or static — and that depends entirely on what you're trying to accomplish, what your network looks like, and whether any additional layers like VPNs or carrier NAT are in play. The steps above surface all the relevant numbers; what you do with them is shaped by your own setup.
