Some ISP have begun replacing their clients’ IPv4 addresses with IPv6. At the moment, IPv4 and IPv6 coexist and will continue to do so for the foreseeable future. IPv4 VS IPv6. IPv4 is based on a 32-bit address scheme which roughly translates into 4 million IPv4 addresses. An IPv4 address consists of four number which are separated by periods.

Internet Protocol version 6 (IPv6) is the latest version of the Internet Protocol (IP) and it became a draft standard in 1998 and later established as Internet Standard in 2017. From the end-to-end connectivity perspective, IPv6 provides better results than IPv4. IPv6-test.com is a free service that checks your IPv6 and IPv4 connectivity and speed. Diagnose connection problems, discover which address(es) you are currently using to browse the Internet, and what is your browser's protocol of choice when both v6 and v4 are available.

The move to IPv6 won’t affect how you access IPv4 content. Websites will look the same, and AT&T will still support your IPv4 devices and networks. But with IPv6, you can connect with more content, more devices, and more people than ever.

IPv6 is better than IPv4 in terms of connectivity. IPv4 is compatible with 32 bit IP addresses whereas, IPv6 supports 128 bit IP addresses providing unlimited IP addresses for the devices to directly communicate to the internet without NAT.

IPv4 vs IPv6: Gaming Zones and even online gaming sites benefit hugely by having IPv6 connectivity since players can experience increased gaming quality despite many devices being connected to one single IPv6 address. The move to IPv6 won’t affect how you access IPv4 content. Websites will look the same, and AT&T will still support your IPv4 devices and networks. But with IPv6, you can connect with more content, more devices, and more people than ever. Until we're an IPv6-only world, Internet Service Providers (ISPs) need to provide their customers with Internet connectivity, whether the host-to-server (you to a website) connection is IPv4-to-IPv4 or IPv6-to-IPv6. Fortunately, there is a plan. Dual stack to the rescue. ISPs have chosen an IP address transition method called dual stack.
