There are three versions of the specification currently available, MoCA 1.1, MoCA 2.0, and MoCA 2.5.
MoCA was established in 2004.
Within the scope of the Internet protocol suite, MoCA is a protocol that provides the link layer. In the 7-layer OSI model, it provides definitions within the data link layer (layer 2) and the physical layer (layer 1). DLNA approved of MoCA as a layer 2 protocol.
In March 2017, SCTE/ISBE society and MoCA consortium began creating a new "standards operational practice" (SCTE 235) to provide MoCA 2.0 with Docsis 3.1 interoperability. Interoperability is necessary because both MoCA 2.0 and Docsis 3.1 may operate in the frequency range above 1 GHz. The standard "addresses the need to prevent degradation or failure of signals due to a shared frequency range above 1 GHz".
MoCA 2.5 (introduced April 13, 2016) offers actual data rates up to 2.5 Gbit/s, continues to be backward interoperable with MoCA 2.0 and MoCA 1.1, and adds MoCA protected setup (MPS), Management Proxy, Enhanced Privacy, Network wide Beacon Power, and Bridge detection.
MoCA Access is intended for multiple dwelling units (MDUs) such as hotels, resorts, hospitals, or educational facilities. It is based on the current MoCA 2.0 standard which is capable of 1 Gbps net throughputs, and MoCA 2.5 which is capable of 2.5 Gbps.

- Channel C4 is commonly used for Verizon FiOS for the "WAN" link from the ONT to the router.
- Channels D1-D8 are commonly used for "LAN" links, between set-top boxes and the router.
- E band channels are commonly used by DirecTV converter boxes. The DirecTV Ethernet-to-Coax Adapter (DECA) uses MoCA on this "Mid-RF" frequency band.
