# Cilium
## IP Address Management (IPAM)
IP Address Management (IPAM) is responsible for the allocation and management of IP addresses used by network endpoints (container and others) managed by Cilium. The default mode is "Cluster Scope".
You can set the following parameters:
```yml
cilium_ipam_mode: cluster-pool
```
### Set the cluster Pod CIDRs
Cluster Pod CIDRs use the kube_pods_subnet value by default.
If your node network is in the same range you will lose connectivity to other nodes
You can set the following parameters:
```yml
cilium_pool_cidr: 10.233.64.0/18
```
When cilium_enable_ipv6 is used, you need to set the IPV6 value:
```yml
cilium_pool_cidr_ipv6: fd85:ee78:d8a6:8607::1:0000/112
```
### Set the Pod CIDR size of a node
When cilium IPAM uses the "Cluster Scope" mode, it will pre-allocate a segment of IP to each node,
schedule the Pod to this node, and then allocate IP from here. cilium_pool_mask_size Specifies
the size allocated from cluster Pod CIDR to node.ipam.podCIDRs
```yml
cilium_pool_mask_size: "26"
```
cilium_pool_mask_size Specifies the size allocated to node.ipam.podCIDRs from cluster Pod IPV6 CIDR
```yml
cilium_pool_mask_size_ipv6: "120"
```
## Kube-proxy replacement with Cilium
Cilium can run without kube-proxy by setting `cilium_kube_proxy_replacement`
