Network Addressing & Host Scope

MA-M

This assignment represents an IEEE MA-M allocation, granting a dedicated boundary of 1,048,576 unique host MAC addresses.

START: 34:D0:B8:80:00:00 1,048,576 Total Addresses END: 34:D0:B8:8F:FF:FF
Lower Bound (Base Host 0) Upper Bound (Top Boundary)
IEEE Registry Tier MA-M Universally Administered (UAA)
Total Host Capacity 1,048,576 Exact binary space: 220 addresses
Derived IPv6 Link-Local SLAAC Base RFC 4291 EUI-64
fe80::36d0:b8ff:fe80:0000

Base address derived from the allocation start, not a network prefix or a verified configured address. The link-local subnet is fe80::/64.

RFC 4291 (Modified EUI-64): This example derives an interface identifier from a 48-bit MAC address by inserting ff:fe and inverting the universal/local bit. An interface can use a different IPv6 identifier.

Octet & Bit Architecture

28-Bit Architecture
Allocation Spread 28-BIT PREFIX (58%) + 20-BIT HOST (42%)
28-Bit Prefix
20-Bit Host
Bit 0 [34:D0:B8:8]
Bit 28
Bit 47 [Host Top]

OUI / Prefix OUI means Organizationally Unique Identifier. MA-L uses a 24-bit prefix; MA-M and MA-S use 28-bit and 36-bit prefixes.

Host bits The remaining bits define the address space within the allocation.

Binary Octet Breakdown (Prefix)

Colored bits in Octet 0 (the first byte) match the I/G and U/L cards below. Octet indices start at zero.

Octet 0 34 0011 01 0 0
Octet 1 D0 1101 0000
Octet 2 B8 1011 1000
Octet 3 (high nibble) 8_ 1000 [Host]
First octet, bit 1 (U/L) b1 = 0
Universally Administered (UAA)

Globally unique IEEE governed address.

First octet, bit 0 (I/G) b0 = 0
Unicast Transmission

Individual address destination (point-to-point transmission).
