CnrPhysAddress
A Layer 1 address which includes the hardware address space as well as the usual MAC address. This object is encoded in ASCII as <type>,<length>,<address> where <type> is the value of the hardware address space field, as used in ARP (i.e, 1 for Ethernet, 6 for token ring...) IANA has a list of registered numbers for this field. <length> is the length of the address, in bytes (not ASCII chars) <address> is the ASCII hex-encoded address (2 ASCII characters per byte; 12 chars for an Ethernet address.) This encoding is intended to mirror the representation of MAC addresses in DHCP.
