Azure Infrastructure: Network infrastructure in a new Subscription

Step 1: Request IP Space:

  • To request IP space, a service now ticket is needed.
  • Using the link servicenow, you can open a General Access & Security request.
  • Filling the form should look like the screenshot below:

  • In the ServiceNow form, I requested an IP space with size of /26 – approximately 60+ IP addresses.
  • Feel free to customize the IP space to your individual need, they typically range between /16, /24, /26.
  • Once the IP Address has been provided, a member of WUIT will reach out directly with the IP space.
  • The email will typically be as follow:

  • To create a new virtual network search vnet or virtual network on the Azure search bar on the azure console.
    1. The first step is to give the virtual network a name and associate it to a subscription and resource group.

Step 3: Perform Virtual network Peering

  • After creating the virtual network with the appropriate IP space, you should reach out back to WUIT either through the ticket or teams to request a virtual network peering.
  • Once, you received confirmation you should go to Virtual Network > Peerings and the peering should appear.
