+## Example Usage
+
+```terraform
+data "bloxone_infra_hosts" "host" {
+  filters = {
+    display_name = "my-host"
+  }
+}
+
+resource "bloxone_dhcp_server" "dhcp_server" {

+}
+
+resource "bloxone_dhcp_host" "example_dhcp_host" {
+  id     = data.bloxone_infra_hosts.host.results.0.legacy_id
+  server = bloxone_dhcp_server.dhcp_server.id
+}
+```

+<!-- schema generated by tfplugindocs -->
+## Schema
+
+### Required
+
+- `id` (String) The resource identifier.
+- `server` (String) The resource identifier.
+
+### Optional
+
+- `retry_if_not_found` (Boolean) If set to `true`, the resource will retry until a matching host is found, or until the Create Timeout expires.
+- `timeouts` (Block, Optional) (see [below for nested schema](#nestedblock--timeouts))
+
+### Read-Only
+
+- `address` (String) The primary IP address of the on-prem host.
+- `anycast_addresses` (List of String) Anycast address configured to the host. Order is not significant.
+- `associated_server` (Attributes) The DHCP Config Profile for the on-prem host. (see [below for nested schema](#nestedatt--associated_server))
+- `comment` (String) The description for the on-prem host.
+- `current_version` (String) Current dhcp application version of the host.
+- `ip_space` (String) The resource identifier.
+- `name` (String) The display name of the on-prem host.
+- `ophid` (String) The on-prem host ID.
+- `provider_id` (String) External provider identifier.
+- `tags` (Map of String) The tags of the on-prem host in JSON format.
+- `tags_all` (Map of String) The tags of the on-prem host in JSON format including default tags.
+- `type` (String) Defines the type of host. Allowed values:  * _bloxone_ddi_: host type is BloxOne DDI,  * _microsoft_azure_: host type is Microsoft Azure,  * _amazon_web_service_: host type is Amazon Web Services.  * _microsoft_active_directory_: host type is Microsoft Active Directory.
+
+<a id="nestedblock--timeouts"></a>
+### Nested Schema for `timeouts`
+
+Optional:
+
+- `create` (String) A string that can be [parsed as a duration](https://pkg.go.dev/time#ParseDuration) consisting of numbers and unit suffixes, such as "30s" or "2h45m". Valid time units are "s" (seconds), "m" (minutes), "h" (hours).
+
+
+<a id="nestedatt--associated_server"></a>
+### Nested Schema for `associated_server`
+
+Read-Only:
+
+- `id` (String) The resource identifier.
+- `name` (String) The DHCP Config Profile name.
