# NAME
docker-network-ls - list networks
# SYNOPSIS
**docker network ls**
[**-f**|**--filter**[=*[]*]]
[**--format**=*"TEMPLATE"*]
[**--no-trunc**[=*true*|*false*]]
[**-q**|**--quiet**[=*true*|*false*]]
[**--help**]
# DESCRIPTION
Lists all the networks the Engine `daemon` knows about. This includes the
networks that span across multiple hosts in a cluster, for example:
```bash
$ docker network ls
NETWORK ID NAME DRIVER SCOPE
7fca4eb8c647 bridge bridge local
9f904ee27bf5 none null local
cf03ee007fb4 host host local
78b03ee04fc4 multi-host overlay swarm
```
Use the `--no-trunc` option to display the full network id:
```bash
$ docker network ls --no-trunc
NETWORK ID NAME DRIVER
18a2866682b85619a026c81b98a5e375bd33e1b0936a26cc497c283d27bae9b3 none null
c288470c46f6c8949c5f7e5099b5b7947b07eabe8d9a27d79a9cbf111adcbf47 host host
7b369448dccbf865d397c8d2be0cda7cf7edc6b0945f77d2529912ae917a0185 bridge bridge
95e74588f40db048e86320c6526440c504650a1ff3e9f7d60a497c4d2163e5bd foo bridge
63d1ff1f77b07ca51070a8c227e962238358bd310bde1529cf62e6c307ade161 dev bridge
```
## Filtering
The filtering flag (`-f` or `--filter`) format is a `key=value` pair. If there
is more than one filter, then pass multiple flags (e.g. `--filter "foo=bar" --filter "bif=baz"`).
Multiple filter flags are combined as an `OR` filter. For example,
`-f type=custom -f type=builtin` returns both `custom` and `builtin` networks.
The currently supported filters are:
* driver
* id (network's id)
* label (`label=<key>` or `label=<key>=<value>`)
* name (network's name)
* type (custom|builtin)
#### Driver
The `driver` filter matches networks based on their driver.
The following example matches networks with the `bridge` driver:
```bash
$ docker network ls --filter driver=bridge
NETWORK ID NAME DRIVER
db9db329f835 test1 bridge
f6e212da9dfd test2 bridge
```
#### ID
The `id` filter matches on all or part of a network's ID.
The following filter matches all networks with an ID containing the
`63d1ff1f77b0...` string.
```bash
$ docker network ls --filter id=63d1ff1f77b07ca51070a8c227e962238358bd310bde1529cf62e6c307ade161
NETWORK ID NAME DRIVER
63d1ff1f77b0 dev bridge
```
You can also filter for a substring in an ID as this shows:
```bash
$ docker network ls --filter id=95e74588f40d
NETWORK ID NAME DRIVER
95e74588f40d foo bridge
$ docker network ls --filter id=95e
NETWORK ID NAME DRIVER
95e74588f40d foo bridge
```
#### Label
The `label` filter matches networks based on the presence of a `label` alone or a `label` and a
value.
The following filter matches networks with the `usage` label regardless of its value.
```bash
$ docker network ls -f "label=usage"
NETWORK ID NAME DRIVER
db9db329f835 test1 bridge
f6e212da9dfd test2 bridge
```
The following filter matches networks with the `usage` label with the `prod` value.
```bash
$ docker network ls -f "label=usage=prod"
NETWORK ID NAME DRIVER
f6e212da9dfd test2 bridge
```
#### Name
The `name` filter matches on all or part of a network's name.
The following filter matches all networks with a name containing the `foobar` string.
```bash
$ docker network ls --filter name=foobar
NETWORK ID NAME DRIVER
06e7eef0a170 foobar bridge
```
You can also filter for a substring in a name as this shows:
```bash
$ docker network ls --filter name=foo
NETWORK ID NAME DRIVER
95e74588f40d foo bridge
06e7eef0a170 foobar bridge
```
#### Type
The `type` filter supports two values; `builtin` displays predefined networks
(`bridge`, `none`, `host`), whereas `custom` displays user defined networks.
The following filter matches all user defined networks:
```bash
$ docker network ls --filter type=custom
NETWORK ID NAME DRIVER
95e74588f40d foo bridge
63d1ff1f77b0 dev bridge
```
By having this flag it allows for batch cleanup. For example, use this filter
to delete all user defined networks:
```bash
$ docker network rm `docker network ls --filter type=custom -q`
```
A warning will be issued when trying to remove a network that has containers
attached.
