Title: DNS ShareCenter - Should I Use DHCP, Static IP, or Reserved IP Address?
Post by: JavaLawyer on February 13, 2014, 06:43:47 AM
The protocol a D-Link ShareCenter uses to connect to a router may cause issues if not properly configured. This FAQ entry describes the different ways a D-Link ShareCenter can connect to a network and the pros and cons of each approach.

1. Basic Definitions

2. DHCP - Dynamic Host Configuration Protocol

DHCP is the default configuration a new D-Link ShareCenter is configured for out-of-the-box. Using DHCP, when the ShareCenter connects to a router, the router will assign an IP address to the ShareCenter that falls within the valid IP address range defined for the router.

DHCP IP address assignment rules:

Sample scenario:

3. Reserving an IP Address

Reserving an IP address is configured from the router web UI (not the ShareCenter). Using this option, the end-user selects a specific IP address for the ShareCenter and reserves the IP address in the router. The reserved IP address will always be made available for the ShareCenter, even if the ShareCenter disconnects/reconnects to the network.

Reserved IP address rules:

Sample scenario:

4. Static IP Address

A static IP address is configured in the D-Link ShareCenter web UI (not the router). A static IP address forces the router to assign a specific IP address to the ShareCenter each and every time the ShareCenter connects to the router. However, there are circumstances where the router may not be able to provide the IP address requested by the ShareCenter.

Static IP address rules:

Sample scenario:

5. Best Approach: Reserved IP Address
