planning to address the network
assigning address to devices
subnetting using the subnet ID
subnetting into the interface ID
100
it was common for organizations to have all computers and other networked devices connected to a single IP network
What is In early network implementations
100
Each host in an internetwork must have a unique address. Without the proper planning and documentation, an address could be assigned to more than one host, resulting in access issues for both hosts.
What is Preventing Duplication of Addresses
100
end user devices often have
What is addresses dynamically assigned
100
IPv6 subnetting requires
What is a different approach than IPv4 subnetting.
100
IPv6 bits can be borrowed from the
What is interface
200
All devices in the organization were assigned an IP address with a matching
What is network ID
200
Some hosts, such as servers, provide resources to internal hosts as well as to external hosts. The Layer 3 address assigned to a server can be used to control access to that server. If, however, the address is randomly assigned and not well documented, controlling access is more difficult.
What is Providing and Controlling Access

DHCP
What is Dynamic Host Configuration Protocol
200
it is subnetted to support
What is hierarchical, logical design of the network.
200
When extending the subnet ID by borrowing bits from the interface ID, the best practice is to
What is subnet on a nibble boundary.
300
In a small network, with a limited number of devices, a flat network design is not
What is problematic
300
Similarly, the security and performance of network hosts and the network as a whole must be monitored. As part of the monitoring process, network traffic is examined for addresses that are generating or receiving excessive packets. If there is proper planning and documentation of the network addressing, problematic network devices can be easily found.
What is Monitoring Security and Performance
300
Any network resource, such as a server or a printer, should have a
What is static IP address

While IPv4 subnetting is about managing address scarcity, IPv6 subnetting is
What is about building an addressing hierarchy based on the number of routers and the networks they support.

A router is necessary for devices on different networks to
What is communicate.

Within a network, there are different types of devices, including:
What is •End user clients •Servers and peripherals •Hosts that are accessible from the Internet •Intermediary devices •Gateway
400
only a few devices are accessible by hosts outside of the corporation
What is In most internetworks

IPv6 address block with a /48 prefix has
What is 16 bits for subnet ID

Subnetting on nibble boundaries means only using
What is nibble aligned subnet masks
500
subnetting creates multiple logical networks from a
What is single address block or network address.

When developing an IP addressing scheme, it is generally recommended to
What is have a set pattern of how addresses are allocated to each type of device

variations in the address of one of these devices will make this device

Subnets created from the subnet ID are easy to represent because there is
What is no conversion to binary required
