logical address and physical address


In a system, there are two types of addresses: logical and physical. Another name for logical address is IP address and it is set by your Internet service provider (ISP) or your router. If you have a router then you have a LAN, which sets a logical address for your computer. Your router will have an logical address set by your ISP.
The physical address is also called the MAC address and it is generated by the manufacturer. (but only to a given extent)

Because a MAC address is assigned (by the FCC) to a company to use for a range of products.
For example:
01:23:45:00:00:00 - 01:23:45:FF:FF:FF
Would be their "range" of MAC addresses. They use a coding called Hex which is not to far off from what you know which is base-10 (0-9).
Instead hex uses (0-F). 0123456789ABCDEF
A = 10, B = 11, etc.
