Please read the following rules:
1. If you are using a <a href="https://cloud.gitlab-pages.ics.muni.cz/documentation/register/#personal-project">PERSONAL</a> project you have to use the `78-128-250-pers-proj-net` network. Use `public-cesnet-78-128-250-PERSONAL` for FIP allocation, FIPs from this pool will be periodically released.
2. If you are using a <a href="https://cloud.gitlab-pages.ics.muni.cz/documentation/register/#group-project">GROUP</a> project you may choose from the `public-cesnet-78-128-251-GROUP`, `public-muni-147-251-124-GROUP` or any other <a href="https://cloud.gitlab-pages.ics.muni.cz/documentation/register/#group-project">GROUP</a> network.

### Personal Project networking
Is currently limited to the common internal network. The network in which you should start your machine is called `78-128-250-pers-proj-net` and is selected by default when using dashboard to start a machine (if you do not have another network created). The floaing IPs you need to access a virtual machine is `public-cesnet-78-128-250-PERSONAL`. Any other allocated FIP and `external gateway` will be deleted. You cannot use router with the personal project and any previously created routers will be deleted.
