Error while Deploying a Template to create a VNet with Custom DNS IP's

Hi All,

I am trying to create a vnet with a subnet. This vnet needs to be configured to have its own custom DNS IP's. But this fails.

Below is the ARM Template that i am using.

=======================================================================

{
    "$schema": "http://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json#",
    "contentVersion": "1.0.0.0",
    "parameters": {
      "location": {
          "type": "string",
          "metadata": {
              "Description": "The region to deploy the resources into"
          }
      },
      "vnetname": {
          "type": "string",
          "metadata": {
              "Description": "The name of the Virtual Network"
          }
      },
      "vnetaddressrange":{
          "type": "string",
          "metadata": {
              "Description": "The Address Prefix of the Vnet in CIDR notation"
          }
      },
      "subnetname":{
          "type": "string",
          "metadata": {
              "Description": "The name of the subnet"
          }
      },
      "subnetaddressrange":{
          "type": "string",
          "metadata": {
              "Description": "The Address Prefix of the subnet in CIDR notation"
          }
      },
      "dnsips":{
          "type": "array",
          "metadata": {
              "Description": "The IP addresses for the DNS Servers"
          }
      }
    },
    "variables": {},
    "resources": [
      {
      "type": "Microsoft.Network/virtualNetworks",
      "name": "[parameters('vnetname')]",
      "apiVersion": "2018-02-01",
      "location": "[parameters('location')]",
      "properties": {
          "addressSpace": {
              "addressPrefixes": [
                  "[parameters('vnetaddressrange')]"
              ]
          },
          "dhcpOptions": {
              "dnsServers": [
                  "[parameters('dnsips')]"
              ]
          },
          "subnets": [
              {
                  "name": "[parameters('subnetname')]",
                  "properties": {
                  "addressPrefix": "[parameters('subnetaddressrange')]"
                  }
              }
          ],
          "virtualNetworkPeerings": [],
          "enableDdosProtection": false,
          "enableVmProtection": false
      }
      }
      ]
  }

=========================================================

The screenshot of the page where I am inputting the values. As soon as i hit Purchase, it gives me validation errors. Below is the screenshot of the same.

==================================================================

Now if i change the parameter "dnsips"  type to "string", it works but only with a single value and not more than one. 

Is there something wrong with the syntax or is there a specific way that i need to input the array value for this to work?

Any clue or guidance pointing what I am doing wrong, would a great help for me.

Thank You.
