# Manage IP Lists

You can configure IPs and CIDRs (Classless Inter-Domain Routing) as IP Lists and add them to an [Administration API application](/docs/applications-and-sso/manage-applications/integrate-api-applications/integrate-administration-api.md). IP Lists restrict user access only to IDaaS Admin API applications linked to the IP addresses included in the IP List. IP Lists can also be associated to IP source addresses in [resource rules](/docs/authentication-and-security/create-and-manage-resource-rules/create-resource-rules.md) to be used to restrict user access based on the IPs defined in the list.
