Dynamic IP Addresses
A dynamic IP address is an IP address that is automatically assigned to a client station (computer, printer, etc.) in a TCP/IP network.
Dynamic IP addresses are typically assigned by a DHCP server, which can be a computer on the network or another piece of
hardware, such as the Router. A dynamic IP address may change every time your computer connects to the network.
Encapsulation
The technique used by layered protocols in which a layer adds header information to the protocol data unit (PDU) from the layer
above. As an example, in Internet terminology, a packet would contain a header from the physical layer, followed by a header from
the network layer (IP), followed by a header from the transport layer (TCP), and followed by the application protocol data.

x is an eight- bit number from 0 to 255. There are three classes: A, B and C, depending on how many computers on the site are likely
to be connected.
