Internet Protocol version 6 (IPv6) is the version recently released from the Internet Protocol (IP), the communications protocol that supplies location system and an identification for devices on networks and transfer traffic through the Internet. It was enhanced by (IETF) to handle the long-anticipated issue of IPv4 address limpness. IPv6 is purposed to replace IPv4, it also increases the count of IP addresses obtainable and improves auto-configuration capabilities of the network and IPv4's routing.

Some Mac OS users complain that even after connecting to b.VPN servers using b.VPN application, their IP address hasn’t changed and they’re not able to access blocked websites in their regions. So here’s the solution.

Now, if you wish to disable IPv6 you will have few steps to make as the following:

Open “Apple menu”. Click “System Preferences”.

Click “Network”. In case it’s locked, you will be required to provide your username and password then click “unlock” button.

Select your current Internet connection. Click “Advanced” button.

Click on “TCP/IP” tab.

Click on “Configure IPv6”.

Choose “Off” then click “OK”.

Restart your PC to save the changes.
