Week 7 discussion
Dq1
DHCP Reservations
Consider the types of systems that benefit from DHCP
reservations and/or from having manually-configured (static) IP addresses,
including servers, networked printers, and other networked devices (e.g.,
network-connected HVAC controllers, IP camera systems). One option is to configure DHCP reservations
and allow the devices to use DHCP to consistently get the same address; another
option is to configure static addresses on the devices themselves and leave the
addresses out of any DHCP scopes (or just to reserve them in DHCP). For the scenarios mentioned above (e.g.,
servers, networked printers, other similar networked devices), would you
recommend static configuration on the devices or DHCP reservations? Why?
Are some types of devices better suited to DHCP than others?
Dq2
DHCP Rebooting Messages
Provide a brief description for each DHCP message that would
be exchanged, in order, if the DHCP server is in the middle of rebooting during
an initial lease request but comes up seconds later. Answers might be slightly different depending
on when you choose exactly for the DHCP server to come online. Feel free to use a diagram if you wish, and
provide a rough description of timing of the messages and/or duration between
them.
Dq3
DHCP Unavailability
Consider a large network with many desktops, laptops, and
networked printers. What are the
advantages and disadvantages of short versus long lease times? Consider if the DHCP server is unavailable
for a short time – what are the impacts if lease time is short, or if lease time
is long? What do you expect is a typical
lease time for most large organizations with desktops, servers, wireless
devices, networked printers and other networked devices (e.g.,
network-connected HVAC controllers, IP camera systems)?
