Change Your IP Address on iPhone

Public IP, local Wi-Fi IP, VPNs and Private Relay explained without mixing them together

First: which IP do you want to change?

An iPhone can have several addresses at the same time. The two most commonly confused are:

Changing the local Wi-Fi address does not necessarily change the public IP. If your goal is to see a different address on websites, you are talking about the public IP.

Method 1: switch between Wi-Fi and cellular

Wi-Fi and cellular normally use different upstream networks, so switching from one to the other will usually change the public IP visible to websites. This is the simplest way to demonstrate the difference between the two network paths.

Method 2: reconnect to your mobile network

Toggling Airplane Mode disconnects and reconnects the cellular session. Your carrier may assign a different public IP or may return the same one; the result depends on the carrier's network design and address pool. Do not assume a new IP is guaranteed.

Method 3: reconnect to Wi-Fi

Forgetting and rejoining a Wi-Fi network can cause your router to assign a different local IP. It usually does not force your ISP to change the router's public internet address. Public IPv4 assignment is controlled upstream by the ISP.

Method 4: use a VPN

A conventional VPN routes supported traffic through a VPN server, so websites normally see the VPN server's public IP instead of the public IP of your current Wi-Fi or cellular connection. After connecting, verify the result at CheckWhatIsMyIP and use the VPN Leak Test to check for separate WebRTC or IPv6 exposure.

Method 5: use iCloud Private Relay for Safari privacy

For iCloud+ subscribers, Apple says Private Relay encrypts traffic leaving the device and sends it through two separate relays, helping prevent websites from seeing the original IP address and exact location for supported browsing. Apple also lets you choose whether the relayed address maintains a general location or uses a broader country/time-zone location. Private Relay is not available in every country or region.

Private Wi-Fi Address is different

Apple's Private Wi-Fi Address feature is about the device identifier used on Wi-Fi networks. It helps reduce tracking based on the Wi-Fi hardware address (MAC address). It should not be described as a way to change your public internet IP.

How to verify what changed

  1. Open CheckWhatIsMyIP before making a network change and note the public IP and ISP.
  2. Make one change — for example Wi-Fi to cellular, enable Private Relay, or connect a VPN.
  3. Reload the page.
  4. If the public IP changed, the website is now seeing a different internet-facing address.
  5. If only the local Wi-Fi address changed, websites may still see the same public IP.
