## Custom DHCP options on Cloudflare One Appliance

May 07, 2026 

[ Cloudflare One Appliance ](https://developers.cloudflare.com/cloudflare-wan/configuration/appliance/)[ Cloudflare One ](https://developers.cloudflare.com/cloudflare-one/)[ Cloudflare WAN ](https://developers.cloudflare.com/cloudflare-wan/) 

When the Cloudflare One Appliance is acting as the DHCP server for a LAN, you can now configure custom DHCP options on the leases it issues. This unlocks workflows such as PXE / iPXE boot, VoIP phone provisioning, and vendor-specific client configuration.

Each option is defined by `option_number`, `value`, and one of four value types: `text`, `integer`, `hex`, or `ip`. Configurations are validated on the appliance before being applied — invalid configurations are rejected and the underlying error is returned to the API caller, so a bad option will not disrupt the live DHCP service.

For details, refer to [DHCP server options](https://developers.cloudflare.com/cloudflare-wan/configuration/appliance/network-options/dhcp/dhcp-options/).
