# DescribeEipNetworkLineTypes

## 1. API Description

This API (DescribeEipNetworkLineTypes) is used to To view the list of IP line types supported by EIP, you can filter by node.

## 2. Input Parameters

The following request parameter list only provides API request parameters.

| Parameter Name | Required | Type   | Description                                                                                        |
| -------------- | -------- | ------ | -------------------------------------------------------------------------------------------------- |
| regionId       | No       | String | <p>Region ID.</p><p>If not provided, it will return all the line types supported by the nodes.</p> |

## 3. Output Parameters
