title: IP Pool Resource (ipPool)
canonical_url: '/reference/calicoctl/resources/ippool'
---

An IP pool resource (ipPool) represents a collection of IP addresses from which Calico expects
endpoint IPs to be assigned.

For `calicoctl` commands that specify a resource type on the CLI, the following
aliases are supported (all case insensitive): `ippool`, `ippools`, `ipp`, `ipps`, `pool`, `pools`.

### Sample YAML

```yaml
apiVersion: v1
kind: ipPool
metadata:
  cidr: 10.1.0.0/16
spec:
  ipip:
    enabled: false
  nat-outgoing: true
  disabled: false
```
