# host-local IP address manager
host-local IPAM allocates IPv4 and IPv6 addresses out of a specified address range.
## Usage
### Obtain an IP
Given the following network configuration:
```
{
"name": "default",
"ipam": {
"type": "host-local",
"subnet": "203.0.113.0/24"
}
}
```
#### Using the command line interface
```
$ export CNI_COMMAND=ADD
$ export CNI_CONTAINERID=f81d4fae-7dec-11d0-a765-00a0c91e6bf6
$ ./host-local < $conf
```
```
{
"ip4": {
"ip": "203.0.113.1/24"
}
}
```
## Backends
By default ipmanager stores IP allocations on the local filesystem using the IP address as the file name and the ID as contents. For example:
```
$ ls /var/lib/cni/networks/default
```
```
203.0.113.1 203.0.113.2
```
```
$ cat /var/lib/cni/networks/default/203.0.113.1
```
```
f81d4fae-7dec-11d0-a765-00a0c91e6bf6
```
## Configuration Files
```

"name": "ipv6",
"ipam": {
"type": "host-local",
"subnet": "3ffe:ffff:0:01ff::/64",
"range-start": "3ffe:ffff:0:01ff::0010",
"range-end": "3ffe:ffff:0:01ff::0020",
