Denial Of Service (DOS) A malicious kind of attack that floods the
intended destination IP address with requests. Example: by pinging 400
to 500 times per second.
DHCP Server Dynamic Host Configuration Protocol is a TCP/IP pro-
tocol that enables PCs and workstations to get temporary or permanent
IP addresses (out of a pool) from a centrally administered server. DCHP
allows a server to dynamically assign IP addresses to workstations
on the fly.
Distributed DOS (DDOS) A distributed denial of service attacks an
intended destination IP address from multiple sources simultaneously
flooding the server. DDOS attacks look like legitimate Internet traffic,
as there is no one single IP address as the source of the attack.
Dialup A type of communication that is established by a switched cir-
cuit connection using the telephone network.
DNS The Domain Name System is a mechanism used in the Internet or
Intranet for translating names to host computers into addresses. DNS
allows host computers not directly on the Internet to have registered
names in the same style. DNS allows you to use the Internet without
remembering long lists of numbers.
DSL Digital Subscriber Line is another name for an ISDN BRI chan-
nel. Operated at the basic rate interface with two 64 Kbps circuit
switched channels and one 16 Kbps packet switched channel.
Dynamic IP A dynamic IP address is an IP address that changes period-
ically. A different IP address may be assigned every time you connect to
the Internet. This makes it more difficult for the others to locate your
computer or other devices from elsewhere on the Internet.
