# gVPC limits and quotas

> The fixed limits for gVPC networks, such as address space, network interfaces per Instance, and MTU.

This page lists the fixed limits for [gVPC](https://datum.net/docs/galactic-vpc/overview.md) networks. gVPC is still being built, and network quotas are not documented yet.

> [!NOTE]
>
> gVPC is in preview, and the `networking.datumapis.com/v1alpha` API can change.

## Limits

| Item | Limit |
| - | - |
| Address space for each network | A `/48` IPv6 prefix that Datum assigns |
| Address space for each location on a network | A `/64` from the network's prefix |
| Address block for each Instance | A `/96` from the location's `/64` |
| Networks for each workload | 1 |
| Network interfaces for each Instance | Exactly 1 |
| Default MTU | `1440` |
| Locations that carry Compute traffic | `us-central-1`, `us-east-1`, and `us-west-1` |

For limits that apply to the workloads on a network, see [Compute limits and quotas](https://datum.net/docs/compute/limits-and-quotas.md). For features that networks don't support yet, see [Limitations and roadmap](https://datum.net/docs/galactic-vpc/limitations-and-roadmap.md).
