Is CMCS Comcast Cable… a VPN or proxy?

No. CMCS Comcast Cable… is classified as a residential ISP network and none of the 10 sampled ranges appears in the datacenter list, so an address from AS33652 normally belongs to a subscriber's home router or phone. That is the profile of a genuine residential IP — the opposite of a VPN or datacenter proxy. Note that residential proxy networks can still route through consumer devices on any ISP, so a clean network is a strong signal, not a guarantee.
