Description

The New-AzVirtualNetwork cmdlet creates an Azure virtual network.

Examples

Example 1: Create a virtual network with two subnets

New-AzResourceGroup -Name TestResourceGroup -Location centralus
$frontendSubnet = New-AzVirtualNetworkSubnetConfig -Name frontendSubnet -AddressPrefix "10.0.1.0/24"
$backendSubnet  = New-AzVirtualNetworkSubnetConfig -Name backendSubnet  -AddressPrefix "10.0.2.0/24"
New-AzVirtualNetwork -Name MyVirtualNetwork -ResourceGroupName TestResourceGroup -Location centralus -AddressPrefix "10.0.0.0/16" -Subnet $frontendSubnet,$backendSubnet

This example creates a virtual network with two subnets. First, a new resource group is created in the centralus region. Then, the example creates in-memory representations of two subnets. The New-AzVirtualNetworkSubnetConfig cmdlet will not create any subnet on the server side. There is one subnet called frontendSubnet and one subnet called backendSubnet. The New-AzVirtualNetwork cmdlet then creates a virtual network using the CIDR 10.0.0.0/16 as the address prefix and two subnets.

Example 2: Create a virtual network with DNS settings

New-AzResourceGroup -Name TestResourceGroup -Location centralus
$frontendSubnet = New-AzVirtualNetworkSubnetConfig -Name frontendSubnet -AddressPrefix "10.0.1.0/24"
$backendSubnet  = New-AzVirtualNetworkSubnetConfig -Name backendSubnet  -AddressPrefix "10.0.2.0/24"
New-AzVirtualNetwork -Name MyVirtualNetwork -ResourceGroupName TestResourceGroup -Location centralus -AddressPrefix "10.0.0.0/16" -Subnet $frontendSubnet,$backendSubnet -DnsServer 10.0.1.5,10.0.1.6

This example create a virtual network with two subnets and two DNS servers. The effect of specifying the DNS servers on the virtual network is that the NICs/VMs that are deployed into this virtual network inherit these DNS servers as defaults. These defaults can be overwritten per NIC through a NIC-level setting. If no DNS servers are specified on a VNET and no DNS servers on the NICs, then the default Azure DNS servers are used for DNS resolution.

Example 3: Create a virtual network with a subnet referencing a network security group

New-AzResourceGroup -Name TestResourceGroup -Location centralus
$rdpRule              = New-AzNetworkSecurityRuleConfig -Name rdp-rule -Description "Allow RDP" -Access Allow -Protocol Tcp -Direction Inbound -Priority 100 -SourceAddressPrefix Internet -SourcePortRange * -DestinationAddressPrefix * -DestinationPortRange 3389
$networkSecurityGroup = New-AzNetworkSecurityGroup -ResourceGroupName TestResourceGroup -Location centralus -Name "NSG-FrontEnd" -SecurityRules $rdpRule
$frontendSubnet       = New-AzVirtualNetworkSubnetConfig -Name frontendSubnet -AddressPrefix "10.0.1.0/24" -NetworkSecurityGroup $networkSecurityGroup
$backendSubnet        = New-AzVirtualNetworkSubnetConfig -Name backendSubnet  -AddressPrefix "10.0.2.0/24" -NetworkSecurityGroup $networkSecurityGroup
New-AzVirtualNetwork -Name MyVirtualNetwork -ResourceGroupName TestResourceGroup -Location centralus -AddressPrefix "10.0.0.0/16" -Subnet $frontendSubnet,$backendSubnet

This example creates a virtual network with subnets that reference a network security group. First, the example creates a resource group as a container for the resources that will be created. Then, a network security group is created that allows inbound RDP access, but otherwise enforces the default network security group rules. The New-AzVirtualNetworkSubnetConfig cmdlet then creates in-memory representations of two subnets that both reference the network security group that was created. The New-AzVirtualNetwork command then creates the virtual network.
