# IPv6 for repo.linuxfabrik.ch and the Mirror Servers

[ Home ](https://www.linuxfabrik.ch/en)     [ Blog ](https://www.linuxfabrik.ch/en/blog)      IPv6 for repo.linuxfabrik.ch and the Mirror Servers    

Better late than never: our package repository, the download server and the mirror servers for RHEL 8, 9 and 10 are reachable over IPv6. Hosts in IPv6-only networks get their packages directly, without NAT64 or a proxy.

## What is reachable over IPv6

All services run dual-stack, IPv4 stays as it is.

- [repo.linuxfabrik.ch](https://repo.linuxfabrik.ch/): RPM and DEB packages, among them the [Linuxfabrik Monitoring Plugins](https://linuxfabrik.github.io/monitoring-plugins/)
- [download.linuxfabrik.ch](https://download.linuxfabrik.ch/): source archives and downloads
- [ip.linuxfabrik.ch](https://ip.linuxfabrik.ch/): returns the public IP address of the calling host, over IPv6 its IPv6 address
- [mirror.linuxfabrik.ch](https://www.linuxfabrik.ch/en/services/mirror-server) and [mirror-rhel8.linuxfabrik.ch](https://www.linuxfabrik.ch/en/services/mirror-server): mirror servers for RHEL 8
- [mirror-rhel9.linuxfabrik.ch](https://www.linuxfabrik.ch/en/services/mirror-server): mirror server for RHEL 9
- [mirror-rhel10.linuxfabrik.ch](https://www.linuxfabrik.ch/en/services/mirror-server): mirror server for RHEL 10

`curl` shows whether your host takes the IPv6 path:

```
$ curl --ipv6 --head https://repo.linuxfabrik.ch/
```

## What to check

**Firewalls with rules per IP address.** If you allow outgoing traffic to our servers by address, add the IPv6 addresses (excerpt):

```
$ dig +short AAAA repo.linuxfabrik.ch
$ dig +short AAAA mirror-rhel9.linuxfabrik.ch
```

**Access to the mirror servers by IP address.** Besides username and password, we also grant access to the mirror servers by source address. These grants apply per address family. A host with IPv6 whose network is registered with us by its IPv4 address only gets a `401 Unauthorized` over IPv6. In that case, send us your IPv6 prefix, or use username and password.

## We help you
