172.27.27.0/24

Nasqueron servers are managed through Drake Network private IPs.

This subnet is divided into 16 subnets of 16 addresses.

✱ denotes currently a false subnet, containing isolated bare metal servers, not linked to any private network excepted through tunnels, with IP are assigned as /32 (netmask 255.255.255.255 0xffffffff)

Servers for the production service mesh. Kubernetes.

Netmask could be:

  • if you need to target the service mesh for access purpose: 255.255.255.248 / 0xFFFFFFF8
  • if you need to address a specific IP of a server: 255.255.255.255 / 0xFFFFFFFF - servers are currently baremetal not linked to any private network ethernet card

Development and management servers. Work by humans should always be from those servers.

Netmask could be:

  • if you need to target the servers humans will use to manage the infrastructure and deploy applications: 255.255.255.248 / 0xFFFFFFF8
  • if you need to address a specific IP of a server: 255.255.255.255 / 0xFFFFFFFF - servers are currently baremetal not linked to any private network ethernet card
