The resulting output is the globally routable IPv6 address of your Mac. These patterns correspond to link-local IPv6 addresses (starting with ‘fe80’), unique local addresses (ULA, starting with ‘fd69’), and the IPv6 loopback address (‘::1’). The second grep command filters out lines containing any of the following patterns: ‘fe80’, ‘fd69’, or ‘::1’. This output is further piped to another grep command with the -E option (to use extended regular expressions) and -v option (which inverts the matching). The output of ifconfig is then piped ( |) to the grep 'inet6' command, which searches for and outputs lines containing the string “inet6”, indicating IPv6 addresses. It begins with the ifconfig command, which displays all network interfaces and their associated configurations. the CLI way (which you can also use in scripts to automate things): ifconfig | grep 'inet6' | grep -E -v '(fe80|fd69| ::1)' The last statement will list the Mac’s IPv6 address.Ģ. System Settings > Network > Your Network interface such as “Wi-Fi” or Ethernet. There are to ways to find your IPv6 address on your Mac: You can get the output from only one single interface with the following command: ifconfig en0 What is my IPv6 Address on Mac? Like stated before, you can also install the iproute2 GNU packages from homebrew to gain access to the regular GNU utils if you prefer those. I still wanted to provide this semi-full output for you to be able to read and understand the different IPv6 addresses on this MacBook Pro which is just connected to WiFi. From what you have learned this far, you should be able to make sense of them all. I excluded about 80% of other output from this command, because it is really long. Inet6 fe80::1%lo0 prefixlen 64 scopeid 0x1 How to display addresses for IPv6 on Mac in Terminal $ ifconfig lo0: flags=804 Please watch my following video with an introduction to IPv6 for the different operating systems, including Mac OS: The following commands are all built-in MacOS commands, no additional 3rd party components! I like to have some of my favorite “gnutils” handy on my Mac. There are also CLI commands for MacOS that I would like to show you.īe aware, that in general you can use most open source GNU core utilities also on a Mac by installing homebrew. Usually the option selected will be Automatic on a regular client. The screenshot above has a manual configuration using the graphical user interface (GUI) highlighted. By default IPv6 on Mac OS, is enabled and does not have to be configured manually, unless you want to. Of course, Apple MacOS or previously OS X have been early to adopt IPv6 and the implementation in Sonoma, Catalina and other recent versions can today be called complete and stable. Let’s have a look at IPv6 support and some history of the Apple MacOS implementation of IPv6, the new Internet Protocol.įor IPv6 on Microsoft Windows and Linux we have silimar guides!
