Use an Amazon-managed prefix list
Amazon-managed prefix lists are created and maintained by Amazon and can be used by anyone with an Amazon account. You cannot create, modify, share, or delete an Amazon-managed prefix list.
As with customer-managed prefix lists, you can use Amazon-managed prefix lists with Amazon resources such as security groups and route tables. For more information, see Reference prefix lists in your Amazon resources.
Amazon-managed prefix list weight
The weight of an Amazon-managed prefix list refers to the number of entries that it takes up in a resource.
For example, the weight of a Amazon CloudFront managed prefix list is 55. Here's how the this affects your Amazon VPC quotas:
Security groups – The default quota is 60 rules, leaving room for only 5 additional rules in a security group. You can request a quota increase
for this quota. Route tables – The default quota is 50 routes, so you must request a quota increase
before you can add the prefix list to a route table.
