Given that IP addresses can be reused over a period of time, blocking IP addresses is riskier than blocking domains or hostnames. So, to avoid false positives, for those external or third-party IP-based feeds like DHS_AIS_IP that are added to policy through voluntary addition (other than what’s provided by default), Infoblox recommends only an ‘Allow-With Log’ policy action and not a ‘Block’ policy action.

Accounts created and configured prior to August 31, 2023 will not be affected by the new default actions and/or precedence described. In the case of prior existing accounts , the actions and precedence in effect at the time of custom list creation will not be altered.
