of telecom operator, actual addresses and users of each IP address.
9) It should be noted that although residential customers are generally assigned dynamic IP addresses
, in actuality, they change infrequently.
In fact, IP addresses
have been one of the major weapons in the fight against credit card fraud, internet predators, and online criminal activities since the internet's invention.
The problem exists because Ethernet networks handle mapping of IP addresses
(those used to find each machine) to MAC addresses (those that uniquely identify a particular machine on the LAN) very informally.
DHCP is a communications protocol found on most networks; it allows network administrators to manage and automate the assignment of IP addresses
in an organization's network.
In the event an iSCSI intelligent storage switch is temporarily off-line, the second storage switch attached to the same storage and the same host network can take over the IP addresses

Domain names make the Internet more easily interpretable to humans than IP addresses
, which are the Internet's underlying system of numerical addresses (IP addresses
are discussed in greater detail ahead).
Commonly, small business and home networks are set up with Internet service that uses a pool of IP addresses
for Internet connectivity, and thus, most have dynamic IP addresses
This growth is creating a glut of IP addresses
, a complex, hard-to-manage networking environment, and a need for automated IP address management.
The consequence of inaccurately configuring DHCP is that end users may not be able to obtain IP addresses
to access the network.
DHCP is employed to manage the IP addresses
of the iSCSI storage elements and the SSCs.
