Find the vendor name of a device by entering an OUI or a MAC address
MAC address 84:83:36 details
24-bit Prefix (MA-L)
Hardware Interface 0x000000 (Min)
Hardware Interface 0xFFFFFF (Max)
Network Addressing & Host Scope
This assignment represents an IEEE MA-L allocation, granting a dedicated boundary of 16,777,216 unique host MAC addresses.
fe80::8683:36ff:fe00:0000Base 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
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.
Colored bits in Octet 0 (the first byte) match the I/G and U/L cards below. Octet indices start at zero.
Globally unique IEEE governed address.
Individual address destination (point-to-point transmission).
