2.  An Internet Protocol address (IP address) is a numerical label assigned to each device (e.g., computer, printer) participating in a computer network that uses the Internet Protocol for communication.  An IP address serves two principal functions: host or network interface identification and location addressing. Its role has been characterized as follows: "A name indicates what we seek. An address indicates where it is. A route indicates how to get there.“  Eg. 172.16.254.1 (for IPv4), and 2001:db8:0:1234:0:567:8:1 (for IPv6).

5.  A numeric identification assigned to a node in a TCP/IP network.  When computers and devices in the network are turned on, they are assigned an IP address by a DHCP server.  A dynamic IP address is an automatically configured IP address assigned by a DHCP server to every new network node.

6.  The public IP address assigned to the routers of most home and business users is a dynamic IP address.  Some Internet Service Providers assign "sticky" dynamic IP addresses that do change but less frequently than a typical dynamic IP address.  A DHCP server assigned IP address is called dynamic because it will often be different on each connection to the network.

7.  IP addresses are most frequently assigned dynamically on LANs and broadband networks by the Dynamic Host Configuration Protocol(DHCP).  They are used because it avoids the administrative burden of assigning specific static addresses to each device on a network.  It also allows many devices to share limited address space on a network if only some of them will be online at a particular time.

8.  In most current desktop operating systems, dynamic IP configuration is enabled by default so that a user does not need to manually enter any settings to connect to a network with a DHCP server.  DHCP is not the only technology used to assign IP addresses dynamically. Dialup and some broadband networks use dynamic address features of the Point-to-Point Protocol.

10. Clients should require no manual configuration by the user to connect to the network. › Each client should be able to discover appropriate configuration information dynamically. › IP address, DNS servers, WINS servers, etc. This is normally accomplished through the use of a Dynamic Host Configuration Protocol- › Uses UDP › Ports 67 and 68

11.  DHCP › Requires little or no administrative overhead, after initial configurations of the DHCP server. › Dynamically maps IP addresses to MAC addresses. › Addresses can be leased for a predefined amount of time before the lease expires and must be renewed by the client. › Allows 30 configuration parameters.

15. One of the primary reasons behind having dynamic IP addresses is the shortage of static IP address on IPv4. Dynamic IP addresses allow a single IP address to be shuffled between many different nodes to circumvent this problem.

16.  Static IP addressing is for one customer on one IP address.  Reliable.  Reserved for statically and don’t change over time.  Residential Internet connections, whether broadband or dialup usually use dynamic IP addresses.  Dynamic IP addressing assigns a different IP address each time the ISP customer logs on to their computer.  Less Reliable.  Change each time you connect to the Internet.  Commercial leased lines and servers have static IPs, so they can always be reached at the same address.

17.  The biggest advantages of Dynamic IP Addressing are less security risk as the computer is assigned a new IP address each time the customer logs on.  They are cost effective.  There is automatic network configuration (the less human intervention with network configuration the better).
