# How to disable IPv6 on iOS (cellular-only) and macOS

[![How to disable IPv6 on iOS (cellular-only) and macOS (see change log) - YouTube](how-to-disable-ipv6-on-ios-cellular-only-and-macos-see-change-log.png)](https://www.youtube.com/watch?v=Nzx9T7GtmT4 "How to disable IPv6 on iOS (cellular-only) and macOS (see change log) - YouTube")

> Heads-up: unfortunately this guide will not work on carriers or ISPs that have migrated their networks to IPv6-only.

## iOS guide

## macOS guide

### Step 1: list network interfaces

```console
$ networksetup -listallnetworkservices
An asterisk (*) denotes that a network service is disabled.
Wi-Fi
iPhone USB
Thunderbolt Ethernet
```

### Step 2: disable IPv6

> Heads-up: use network interfaces found in [step 1](#step-1-list-network-interfaces) (most computers only have `Wi-Fi` interface)

```shell
networksetup -setv6off "Wi-Fi"
networksetup -setv6off "iPhone USB"
networksetup -setv6off "Thunderbolt Ethernet"
```

## Want things back the way they were before following this guide? No problem!

### Step 1 (on iPhone): remove provisioning profile

Open “Settings”, then “General”, then “Profile”, and tap provisioning profile, then “Remove Profile”.

### Step 2 (on Mac): set network interfaces to automatic

```shell
networksetup -setv6automatic "Wi-Fi"
networksetup -setv6automatic "iPhone USB"
networksetup -setv6automatic "Thunderbolt Ethernet"
```
