# Changing Dozzle's Hostname
|
|
|
|
Dozzle's default connection is called localhost. Using the `--hostname` flag, Dozzle's name can be changed to anything. This value will be shown on the page title and under the Dozzle logo.
|
|
|
|
Changing the label for localhost also changes the label for the `localhost` connection which is displayed under the multi-host menu. Below is an example of using `--hostname` to change the name of Dozzle's subheader to `mywebsite.xyz`.

```sh
|
|
docker run --volume=/var/run/docker.sock:/var/run/docker.sock -p 8080:8080 amir20/dozzle --hostname mywebsite.xyz
|
|
```

## Multi-Host and Agents
|
|
|
|
`--hostname` only relabels the host running **this** Dozzle process. Remote [agents](/guide/agent) advertise their own names — set `DOZZLE_HOSTNAME` (or `--hostname`) on each agent to control how it appears in the multi-host menu. In [swarm mode](/guide/swarm-mode) each node runs its own agent, so give each node a distinct hostname to tell them apart.
