It is recommended that static addresses are not within any configured dynamic Network Ranges:![](https://cdn.document360.io/763c5fb1-b9af-4ccd-9ad6-cf28ae4cd5a3/Images/Documentation/Nodegrid_DHCP_Hosts.PNG)

  2. **Enter details:**
    - **Hostname:** An arbitrary identifier for the host
    - **HW Address (optional):** The MAC address used to identify the host**.** When a device with this MAC address asks for a DHCP lease, it will be associated with this Host entry and assigned the static IP. Either **HW Address** or **Agent Circuit ID**, or both, must be configured
    - **Agent Circuit ID (optional):** A vendor-defined "circuit" identifier. Either ****HW Address**** or ****Agent Circuit ID****, or both, must be configured
    - **Assigned Hostname (Option 12) (optional):** A hostname that will be sent and may or may not be honored by the requesting client
    - **IP Address:** The static address to assign to this host**.** It is recommended that this address does not fall within any configured dynamic Network Range
    - Click **Save**
