How to Configure a Private Network on Windows Server

<?xml encoding="utf-8" ??>

Introduction

Vultr provides many flexible networking options for your cloud servers. In addition to the public network attached to every Vultr instance, you can configure up to five private networks per location. Private networks allow instances within a location to communicate without exposing the traffic to the public internet.

Note: Your network adapter names may not match the examples. See our article How to Find the Network Adapter Names for a Vultr Cloud Server.

Please see the guide How to Configure a Private Network at Vultr for general information about Vultr's private network feature.

Private networks do not have DHCP. When deploying a Vultr cloud server with private networking, you must manually configure the private adapters or supply your own DHCP server. We provide network configuration examples for many popular operating systems, pre-configured for your instance's IP addresses. You can find these by navigating to the settings screen (1) for your server, then selecting IPv4 (2). Follow the networking configuration link (3) to view the configuration examples.

The configurations in the customer portal are your best source of specific information. Please see below for step-by-step instructions with generic examples.

Windows Server 2012 R2, Windows Server 2016, Windows Server 2019

Find the private interface name on your system. You can use ipconfig /all or navigate the Windows Control Panel.

Replace "Ethernet 2" with the private interface name that Windows has chosen and run the following command. Replace 10.10.10.3 with your IP address.

netsh interface ip set address name="Ethernet 2" static 10.10.10.3 255.255.0.0 0.0.0.0 1

Manage Private Networks via API

The Vultr API offers several endpoints to manage private networks.
