## Request

This section describes the request format. The method and URI are as follows:

| Method | URI |
| --- | --- |
| GET | /loadbalancer/v2/getLoadBalancerInstanceList |

### Request headers

### Request query parameters

You can use the following query parameters with your request:

| Field | Type | Required | Description |
| --- | --- | --- | --- |
| `loadBalancerInstanceNoList.N` | String | Optional | List of load balancer instance numbers - Example: loadBalancerInstanceNoList.1=123&loadBalancerInstanceNoList.2=345 |
| `networkUsageTypeCode` | String | Optional | Load balancer network type - `PBLIP` \| `PRVT` - `PBLIP` (Public): Public IP - `PRVT` (Private): Private IP |
| `regionNo` | String | Optional | Region number - `1` (default) - `1` (KR): Korea Region - See [getRegionList](/docs/en/compute-server-getregionlist). |
| `zoneNo` | String | Optional | Zone numberSee [getZoneList](/docs/en/compute-server-getzonelist).Query by zone number when entering both Region and zone numbers. |
| `pageNo` | Integer | Optional | Page number of the paged results - 0-2147483647 |
| `pageSize` | Integer | Optional | Number of results to display on a page - 0-2147483647 |
