Create PeerAsn to associate your ASN with Azure Subscription

As an Internet Service Provider or Internet Exchange Provider, you can create a new PeerAsn resource to associate an Autonomous System Number (ASN) with an Azure subscription. You can associate multiple ASNs to a subscription by creating a PeerAsn for each ASN you need to associate.

  1. Sign in to the Azure portal.

  2. Go to the Associate a Peer ASN page.

  3. On the Associate a Peer ASN, enter or select the following values in the Basics tab:

    Setting Value
    Project details
    Name Enter a name for the PeerASN resource that you're creating.
    Subscription Select your Azure subscription that you want to associate the ASN with.
    Instance details
    Peer name Enter your company name. This name must be as close as possible to your PeeringDB profile.
