Acronym for

media access control address
|
Internet Protocol Address
|
Used for
|
It is a unique identifier that is
assigned to network interfaces for communicating on the physical network
segments.
|
It is a numerical value that is assigned
to all the participating devices in a network. i.e. Servers, Computers,
Printers, WAP, Laptops etc.
|
Provided BY
|
It is generally provided by the
manufacturer of the NIC cards and is stored in its hardware.
|
It is provided by the ISP (Internet
Service Provider) or by the Network Administrator.
|
Length
|
It is 48 bit address which contains 6
groups of 2 hexadecimal digits, separated by either hyphens (-) or colons (:)
E.g. 00:FF:FF:AB:BB:AA
Or 00-FF-FF-AB-BB-AA
|
IPv4 uses 32 bit address in dotted
notations, whereas IPv6 Uses 128 bit address in hexadecimal notations.
e.g. IPv4 192.168.1.1
IPv6 FFFE:F200:3204:0B00:
0122:4555:8001:AB00
|
Use of Classes
|
No classes are used in MAC addressing.
|
IPv4 uses A,B,C,D,E classes for IP
addressing
|
Static Vs Dynamic
|
Although intended to be a permanent and
globally unique identification but it is possible to change the MAC address
on most modern hardware.
|
IP address can be static or dynamic. i.e.
a fixed IP can be assigned to device (Computer/ Printer/ Server) or it may
have dynamic IP that can change its value on every boot.
|
Spoofing
|
MAC spoofing Possible.
|
IP Address Spoofing Possible.
|
Address Sharing
|
MAC Address Sharing is not allowed and
unique MAC address is assigned to each NIC.
|
Multiple client devices can share IP
addresses: either because they are part of a shared hosting web server
environment or because an IPv4 network address translator (NAT) or proxy
server acts as an intermediary agent on behalf of its customers.
|
Subnetting
|
No subnetting is used.
|
IP networks may be divided into
subnetworks in both IPv4 and IPv6
