IP Addresses
The homelab uses the 10.0.0.0/8 private address space for internal networking.
Each site is allocated a specific /16 block. To maintain consistency, subnets within these blocks follow a standardized pattern across all locations.
Site Allocations
| Site | IPv4 Range | IPv6 Range |
|---|---|---|
| Vienna (VIE) | 10.0.0.0/16 | 2a01:aea0:dd3:25a::/64 |
| Munich (MUC) | 10.1.0.0/16 | fd40:2e3:42a::/64 |
Cluster Networks
Standardized CIDRs for Kubernetes networking across sites:
| Description | Vienna (VIE) | Munich (MUC) |
|---|---|---|
| POD CIDR | 10.101.0.0/16 | 10.102.0.0/16 |
| Service CIDR | 10.105.0.0/16 | 10.106.0.0/16 |
| Load Balancer CIDR | 10.111.0.0/16 | 10.112.0.0/16 |
General Allocations
For details on how individual IPs are assigned within a site’s main CIDR (e.g., for routers, switches, and servers), see the Main CIDR / General Use page.
