What internet protocol (IP) connectivity modes are supported in DOCSIS 3.0 and 3.1?

The correct response identifies the various IP connectivity modes supported in DOCSIS 3.0 and 3.1 networks. Both protocols, IPv4 and IPv6, are vital for facilitating internet communication.

DOCSIS (Data Over Cable Service Interface Specification) has evolved to support both IPv4 and IPv6, reflecting the growing need for more unique IP addresses as the number of connected devices increases. The inclusion of alternate provisioning mode (APM) allows for different configurations depending on the device capabilities, while dual-stack provisioning mode (DPM) enables simultaneous use of both IPv4 and IPv6, making the transition smoother for service providers and customers alike.

This flexibility in connectivity modes is essential for maintaining compatibility with existing systems, while also preparing for a future where IPv6 becomes more prevalent as IPv4 addresses become scarcer. By supporting multiple modes, DOCSIS 3.0 and 3.1 provide a robust framework for a variety of networking environments.
