5.2
If a DHCP server can't be contacted, the host uses APIPA to assign itself an IP address.
APIPA
The host is configured to obtain IP information from a DHCP server (this is the default configuration).
APIPA
The host only configures the IP address and mask. It does not assign itself the default gateway and DNS server addresses. For this reason, APIPA can only be used on a single subnet.
APIPA
When you configure an alternate IP address, ______ is no longer used.
APIPA
hosts assign themselves an IP address on the 169.254.0.0 network (mask of 255.255.0.0).
APIPA
is a Microsoft implementation of automatic IP address assignment without a DHCP server.
APIPA
use As a fail safe for when a DHCP server is unavailable to provide limited communication capabilities.
APIPA
use On small, single-subnet networks where you do not need to customize the IP address range.
APIPA
Any client configured to use DHCP can get an IP address from any server configured for DHCP, regardless of operating system.
...
If a DHCP server cannot be contacted, the static configuration values are used.
...
Periodically and when the client reboots, it contacts the DHCP server to renew the lease on the IP address.
...
The DHCP lease process uses frame-level broadcasts. For this reason, DHCP requests typically do not pass through routers to other subnets. To enable DHCP across subnets: Enable BootP (DHCP broadcast) requests through the router. Configure a computer for BootP forwarding to request IP information on behalf of other clients.
...
Use DHCP for small, medium, or large networks. DHCP requires a DHCP server and minimal configuration.
...
is a TCP/IP protocol.
DHCP
uses frame-level broadcasts.
DHCP lease process
When a client boots, it contacts the _______ for IP configuration information.
DHCP server
can also be configured to pass out other IP configuration such as the default gateway and DNS server addresses.
DHCP server
can be configured to not assign specific addresses in the range, or to assign a specific address to a specific host.
DHCP server
ensures that each client has a unique IP address.
DHCP server
is a special server configured to pass out IP address and other IP configuration information to network clients.
DHCP server
the system attempts to use DHCP for TCP/IP configuration information.
alternate IP configuration
use If you have a computer (such as a laptop) that connects to two networks: one with a DHCP server and another without a DHCP server.
alternate IP configuration
use If you want to provide values to properly configure the computer in case the DHCP server is unavailable.
alternate IP configuration
The DHCP server assigns the IP address and other information to the client. The assignment is called a
lease
that identifies how long the client can use the IP address.
lease time
You can configure a DHCP server to deliver the same address to a specific host each time it requests an address. Microsoft calls this configuration a
reservation.
The DHCP server is configured with a range of IP addresses it can assign to hosts (Microsoft calls these ranges
scopes
For hosts that cannot accept an IP address from DHCP.
static addressing
IP configuration information must be manually configured on each host.
static addressing
On networks that do not change often or that will not grow.
static addressing
On networks with a very small number of hosts.
static addressing
To permanently assign IP addresses to hosts that must always have the same address (such as printers, servers, or routers).
static addressing
To reduce DHCP-related traffic.
static addressing
also disables both APIPA and DHCP capabilities on the host.
static addressing
is very susceptible to configuration errors and duplicate IP address configuration errors (two hosts that have been assigned the same IP address).
