Want to use IPv6 only instead of IPv4 on your Mac? You have the option to do that. Read on to know how.
Switch Over to IPv6 Completely and Ditch IPv4 on Your Mac - Works on All Mac Models
IPv6 has been around for more than 10 years, and needless to say that it has seen (somewhat) steady adoption around the globe. Slowly and gradually, the whole Internet will switch over to IPv6 and that's a good thing as it offers a lot of great features for internet users.
For example, IPv6 allows transfer of bigger packets of data at once compared to IPv4. If you're constantly downloading and uploading huge files, then IPv6 makes sure things are as fast as possible for you as it doesn't involve unnecessary overhead like IPv4. But that's not all, IPv6 offers overall better performance compared to IPv4 in a lot of cases.
I'm not going to dive into too much technical detail regarding IPv6 as there are a ton of articles and videos highlighting that. If you're interested in knowing more about IPv6 and IPv4, a quick online search will enlighten you in many different ways.
Since IPv6 has a lot of advantage over IPv4, it's best to switch over your devices to IPv6 completely, if your ISP supports it and the feature is enabled on a modem and router level. Assuming that's the case, I'm going to show you how you can use IPv6 only you Mac and disable IPv4 completely.
Again, this is only possible if your ISP supports IPv6 and does so properly. There are a lot of ISPs around the globe that have half-baked IPv6 support and you're better off using IPv4 instead. But, if you're sure your ISP does a mega good job with IPv6 and you want to get rid of IPv4 completely from your life then read on further.
Tutorial
Step 1. Connect to your Wi-Fi network on which you want to use IPv6 only.
Step 2. Click on the Wi-Fi logo in the menu bar and then click on Wi-Fi Settings.
Step 3. Now click on Details next to the connected Wi-Fi.
Step 4. Click on TCP/IP from the left.
Step 5. By default, Configure IPv4 will be set to Using DHCP. Change it to Off.
Step 6. Click on OK to save changes. That's all.
macOS is designed in such a way that it will switch between IPv4 and IPv6 whenever needed. But since you've made the switch to IPv6 completely, I will highly recommend testing out the change you just made properly before settling down and using it exclusively. If you believe the internet seems broken in certain places, it definitely will be as the whole internet is not IPv6 ready, you'd want enable IPv4 right away.
Follow the above steps again - in step 5, just change Off to Using DHCP and save the changes.
Once again, while your ISP may advertise itself as being IPv6 ready, there are slight chances that it has a bad implementation of it. Therefore, a through test with IPv4 disabled will reveal whether you're better off with IPv6 only or run IPv4 alongside it.
In a lot of cases, IPv6 always come out on top when it comes to overall internet performance. IPv6 is extremely efficient at routing and can handle more data packets and deliver them to your devices with no overhead. Ever noticed how your device takes a while connecting to your router at times? With IPv6 enabled, this issue is usually resolved in a lot of cases, unless you just have a bad Wi-Fi router, hence an upgrade might be necessary.
