## Abstract

Described herein are systems, methods, and apparatuses for device communication over IP. In some embodiments, IPv6 addresses are compressed into ISO/IEC 14908-1 addresses, and use leading zero suppression to compress the headers. In some embodiments, IPv4 the least significant two bytes of the IPv4 address are used as an ISO/IEC 14908-1 subnet and node number.

## Claims

### Claim 1

A method comprising:
receiving a first packet at a mapping logic, wherein the first packet comprise a source Control Network Protocol (“CNP”) address and a destination CNP address;
determining a source IP address of the sender of the first packet from the source CNP address;
determining a destination IP address for the first packet;
forming a second packet without including the destination CNP address, wherein the second packet comprises the source IP address formed from the source CNP address, the destination IP address, and a payload that consists the source CNP address and an original payload of the first packet.

### Claim 2 (depends on 1)

The method of claim 1, wherein the source CNP address contains a globally unique identifier.

### Claim 3 (depends on 2)

The method of claim 2, wherein the globally unique identifier is a media access control address (MAC address) of a source device.

### Claim 4 (depends on 1)

The method of claim 1, wherein the destination IP address is an arbitrary address not derived from the destination CNP address.

### Claim 5 (depends on 4)

The method of claim 4, wherein the destination IP address is assigned by a DHCP server.

### Claim 6

An apparatus comprising:
a processor; and
memory to store mapping logic instructions, which when executed by the processor to cause the processor to:
receive a first packet, wherein the first packet comprise a source Control Network Protocol (“CNP”) address and a destination CNP address,
determine a source IP address of the sender of the first packet from the source CNP address,
determine a destination IP address for the first packet,
form a second packet without including the destination CNP address, wherein the second packet comprises the source IP address formed from the source CNP address, the destination IP address, and a payload that consists the source CNP address and an original payload of the first packet.

### Claim 7 (depends on 6)

The apparatus of claim 6 wherein the source CNP address contains a globally unique identifier.

### Claim 8 (depends on 7)

The apparatus of claim 7 wherein the globally unique identifier is a media access control address of a source device.

### Claim 9 (depends on 6)

The apparatus of claim 6 wherein the destination IP address is an arbitrary address not derived from the destination CNP address.

### Claim 10 (depends on 9)

The apparatus of claim 9 wherein the destination IP address is assigned by a DHCP server.
