# Networks
## Overview
The Spearhead Cloud provides rich networking facilities for your containers and virtual machines. Each container/vm gets a full IP stack and you can define your own networks to create complex environments.
## Types of Networks
Spearhead Cloud provides two types of networks by default.
1. **Networks defined by us**. These are networks we create for tasks such as providing internet access or for private access (non-routable). These networks are usually shared by many customers.
2. **Networks defined by you**. These types of networks are sometimes called VXLAN or overlay networks. These networks are private and may be used to isolate applications or segments of your virtual network topology.

> Spearhead Cloud creates a default VLAN with id 2 in all datacenters. This network is private and only accesible by your instances.

## Public network
2018-07-26 19:53:53 +03:00
Spearhead Cloud provides a public network named "External" which you can use to attach your vm's to for direct public Internet access.

Here is an example provisioning an instance explicitly using the External network:
```spearhead create -n nginx03 -N External e74a9cd0 468c03e2```
Here is an example of launching a docker container with a full IP stack on the public Internet.
```spearhead-docker --tls run -d -P 443 --network External d03e867e8cfe```
Docker containers require explicit mapping of networks/ports. If you do not specify a network, the default fabric vlan will be used (i.e. no public IP for your containers).
