Subnet Mask

DHCP Server Settings
Enable DHCP
Server
Click this checkbox to enable the use of a Dynamic
Host Configuration Protocol (DHCP) Server on the
network.
DHCP is a set of rules used by devices such as a
computer, router, or network adapter to allow the
device to request and obtain an IP address from a
server which maintains a list of addresses available
for use.
The DHCP server ensures that all IP addresses are
unique, e.g., no IP address is assigned to a second
device while the first device's assignment is valid
(its lease has not expired).
Without DHCP, the IP addresses must be entered
manually at each computer in an organization, and
a new IP address must be entered each time a
computer moves to a new location on the network.
Start IP
Address/End IP
Address
Enter the range of IP addresses that the DHCP
Server will be allowed to assign to a network
device.
Lease Time
Select the time before the assigned IP address will
expire. (After the lease time is up, the user is
automatically assigned a new dynamic IP address.)
A "lease" is the amount of time that a given IP
address will be valid for a computer or other
network device. The lease time can vary depending
on how long a user is likely to require the Internet
connection at a particular location. Using very short
leases, DHCP can dynamically reconfigure networks
where there are more computers than available IP
addresses, such as educational environments.
Domain Name
Enter the domain name that you want to display on
client devices.
