What’s the difference between IPv4 and IPv6?
With 32 bits, IPv4 addresses have 4 numbers separated by periods:
144.160.155.43
By using 128 bits, IPv6 can include numbers, letters, and longer addresses.
2001:1890:1c00:3113::f:3005
With so many possible combinations, IPv6 can accommodate virtually unlimited devices and websites.
Are we leaving IPv4 content behind?
No. 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.
