Networking¶
IPv4 Networking¶
IPv4 Personal Floating IPs¶
It is currently limited to the common internal networks. You can start your machine in the 147-251-115-pers-proj-net network and allocate floating IP address from the public-muni-147-251-115-PERSONAL pool. You can also try 78-128-250-pers-proj-net network and allocate IP adress from public-cesnet-78-128-250-PERSONAL, but this network is not recommended as in we often see no available addresses there. Keep in mind that you should use matching network and public FIP pool (recommended: 147-251-115-pers-proj-net + public-muni-147-251-115-PERSONAL) as OpenStack does not allow you to associate FIP address from mismatching pool with message External network <ID> is not reachable from subnet <ID>. Therefore, cannot associate Port <ID> with a Floating IP.... All VMs need to be connected to the same network. You cannot use virtual routers with personal projects. We encourage users to also use IPv6 addresses for long term use. Unassigned allocated addresses are released daily.
IPv4 Group Floating IPs¶
The situation is rather different for group projects. You cannot use the same approach as for personal projects. You should create a virtual network as described on page Create networking instead and select one of the pools with -GROUP suffix as show on page Allocating floating IPs. Namely:
public-cesnet-78-128-251-GROUPpublic-cesnet-195-113-167-GROUPpublic-muni-147-251-21-GROUPpublic-muni-147-251-124-GROUP
Warning
Addresses that are unassigned for longer than 3 months can be released.
Tip
If you use a MUNI account, you can use private-muni-10-16-116 and log into the network via MUNI VPN or you can set up Proxy networking, which is described on page Proxy networking. Please pay attention to the fact that there can be Issues with proxy in private networks.
IPv6 Networking¶
IPv6 Shared Network¶
We have prepared an IPv6 prefix public-muni-v6-432, which is available for both personal and group projects. The network is available as an attachable network for VMs with no limits. For more information, refer to the Attaching interface section.
