For example, the following command is used when initializing Swarm:
```bash
$ docker swarm init --default-address-pool 10.20.0.0/16 --default-addr-pool-mask-length 26`
$ docker swarm init --default-addr-pool 10.20.0.0/16 --default-addr-pool-mask-length 26`
```
Whenever a user creates a network, but does not use the `--subnet` command line option, the subnet for this network will be allocated sequentially from the next available subnet from the pool. If the specified network is already allocated, that network will not be used for Swarm.

Docker allocates subnet addresses from the address ranges specified by the `--default-addr-pool` option. For example, a command line option `--default-addr-pool 10.10.0.0/16` indicates that Docker will allocate subnets from that `/16` address range. If `--default-addr-pool-mask-len` were unspecified or set explicitly to 24, this would result in 256 `/24` networks of the form `10.10.X.0/24`.
The subnet range comes from the `--default-addr-pool`, (such as `10.10.0.0/16`). The size of 16 there represents the number of networks one can create within that `default-addr-pool` range. The `--default-address-pool` option may occur multiple times with each option providing additional addresses for docker to use for overlay subnets.
