Appendix B: Assigning a Fixed IP to your DVR
DHCP Scope
A DHCP scope is a range of IP addresses that your router can immediately assign to
devices. A common DHCP scope is 100-255, although this varies between router models
(check your router’s owner’s manual for more information). If the DHCP scope is 100-255
and the router’s IP address is 192.168.1.1, this means that devices that connect using
DHCP will be given an address in the range of 192.168.1.100 to 192.168.1.255. IP addresses
between 192.168.1.2 and 192.168.1.99 are available for fixed assignment.
Fixed IPs
Setting a fixed IP on the router tells the router to reserve an IP address to a particular
device. The fixed IP number is saved onto the router, and remains saved even if the router
is powered off. Likewise, a fixed IP address must also be specified in your DVR so that even
if your DVR turns off, the IP address of the DVR remains the same. The fixed IP address
must be assigned in the DVR and must not be used by any other device on the network. The
end result is that you can power on and off the router and DVR, and the router will always
assign the same IP address to the DVR.
Setting up a Fixed IP Address
NOTE: These are guidelines on how to create a fixed IP. This example is using a Linksys
E2500 router. Additional configuration may be required on your router. Refer to your
router’s owner’s manual for details. The instructions below are for reference only.
Step 1 of 2: Determine the DHCP Scope of the Router:
1 Open an Internet browser and enter the router‘s IP address in the address bar. Log in with
the router‘s user name and password.
2 Select the Setup tab. Then select the Basic Setup tab.
