Technology is changing for all companies that provide broadband access. The number and types of devices using the Internet have increased dramatically in recent years and, as a result, address space for these devices is being rapidly exhausted. Today’s technology for IP addresses is referred to as IPv4 (Internet Protocol version 4). The IP addresses aligned with IPv4 are expected to be depleted at some point in the near future. The next generation of IP address space is IPv6, which contains many more features (like enhanced security) and a virtually limitless number of addresses. Unfortunately, most servers and other Internet devices will not be speaking IPv6 for a while – IPv4 will remain an entrenched standard for some time to come.
To best serve our customers during this time, Verizon is rolling out IPv6 address space in a "dual stack" mode – where IPv4 and IPv6 addresses are both loaded. The company will maintain IPv4 for those servers continuing to use that standard, and IPv6 for servers using this latest standard. The dual stack approach applies to both existing and new Verizon customers
