1. Classful IP addresses: Classful addresses are IP addresses that use a
de- fault subnet mask, as follows: Class A: 255.0.0.0, Class B:
255.255.0.0, Class C: 255.255.255.0
2. VLSM: Variable Length Subnet Masking (VLSM) is the method used to
divide an IP address into subnets of different sizes. When using VLSM,
you ignore the default subnet mask boundaries and specify a custom
number of subnet mask bits
3. Subnetting: The process of dividing a large network into smalle
networks.
4. Supernetting: The process of combining two or more networks
5. Classless Inter-Domain Routing (CIDR): A set of internet protocol
standards used to create unique identifiers for networks and host
devices
6. ANDing: The process used to determine the network address/ ID
7. Subnet Mask: A 32-bit number that defines which portion of an IPv4
address identifies the network address and which portion of the
address defines the host address
8. Network ID: A 32-bit number that identifies network an IPv4 address
belongs to
9. APIPA (Automatic Private IP Addressing): Provides an option for
automatic IP address assignment without a DHCP server. APIPA is
enabled by default on most modern operating systems, including

, TestOut Network Pro Chapter 5
Windows and Linux.
10.Alternate IP Configuration: A manual configuration of a computer's IP
address, default gateway, DNS server address, and WINS address. This
configuration is used if the DHCP server fails to provide this similar
information.
11.DHCP Discover (D): The client begins by sending out a DHCP Discover
frame to identify DHCP servers on the network.
12.DHCP (O): A DHCP server that receives a Discover request from a
client responds with a DHCP Offer advertisement, which contains an
available IP address. If more than one DHCP server responds with an
offer, the client usually responds to the first offer that it receives.
13.DHCP Request (R): The client accepts the offered IP address by
sending a DHCP request back to the DHCP server.
14.DHCP ACK (A): The DHCP server responds to the request by sending
a DHCP ACK (acknowledgement). At this point, the IP address is leased
to and configured on the DHCP client.
15.RFC 1542 Compliant Router: An RFC 1542 compliant router listens for
DHCP traffic and routes any received DHCP frames to the appropriate
subnet.
16.DHCP Relay Agent: A function of the Routing and Remote Access
service (RRAS) role on a Windows server, the DHCP Relay Agent service
sends the DHCP packets it receives to a remote DHCP server on a
different subnet.
17.. (dot) domain: The . (dot) domain, also called the root domain,
denotes a fully qualified, unambiguous domain name.
