ANSWER:
IPv6 is the most recent version of the IP protocol (Internet Protocol). The IPv6 address was developed as a solution in case IPv4 addresses were exhausted, but in practice, there are limited use cases for IPv6. Internet services primarily rely on IPv4 for network communication since IPv4 is most widely used and supported.
Cable Multi Service Providers (MSOs, such as Comcast, Time Warner/Spectrum, Cable One, etc.) assign a unique IP address to every device connected to their networks. This process is automatic, and you don’t have to configure anything, whether your MSO supports IPv6 or the older IPv4.
A typical IPv6 address contains eight groups of four hexadecimal digits, with the groups separated by colons, e.g. 2001:0db8:0000:0000:0000:ff00:0042:1234. The IPv4 address format specifies four pairs of hexadecimal digits(often written as the equivalent decimal values), with each pair separated by periods, e.g. 192.168.0.1
All of Motorola’s modems and gateways support IPv6 as well as the older IPv4 protocols, including their respective address formats.
