Define an ASN for a dynamic zone

Define an ASN for your dynamic zone that is used to uniquely identify each network on the internet. Since the ASN represents an entire network of IP addresses, specifying an ASN can help you reduce overhead as an alternative to entering a list of multiple IP addresses.

Before you begin

Create a dynamic zone. See Create a dynamic zone.

Define ASN for a dynamic zone

  1. In the Admin Console, go to Security > Networks.

  2. Select an existing dynamic zone and click Edit.
  3. In ISP ASNs, use the ASN Lookup tool to retrieve the ASN.
  4. Enter the ASN to include it as part of the dynamic zone.
  5. To block ASNs, select the Block access from IPs matching conditions listed in this zone checkbox.
  6. Click Save.

Whenever you edit a network zone, you need to wait approximately 60 seconds for the change to propagate across all servers and take effect.
