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:

1Open an Internet browser and enter the router‘s IP address in the address bar. Log in with the router‘s user name and password.

2Select the Setup tab. Then select the Basic Setup tab.
