Utilizing a DOCSIS 3.0 CM (Hitron Tech / ZyXEL BRG-35503) with Spectrum. The modem is not on their compliant list. The CM is getting a private 10.0.0.0/8 Spectrum IPv4 WAN address but not a IPv6 address. Likewise systems (Windows 10, Ubuntu 20, OpenWrt) directly wired to the CM obtain a public IPv4 address but no public IPv6 address.
The CM appears to be configured with MEMO and MdCfgIpProvMode set to MDD.
Spectrum has stated they provide IPv6 (dual-stack actually) in my area. When pressed, they find it difficult to support this statement.
Looking for guidance on debugging this issue. Is there a way to determine if the CMTS is DOCSIS 3.0 or greater compliant and configured to support dual-stack? Are there other configuration parameters of the CM that I should be attempting to examine and possibly set? Are there logs that can be viewed or network traffic that can be examined to gain further insight?
