Legacy Network Subnet Inventory - 192.168.0.0/16

This document provides a comprehensive inventory of all subnets within the 192.168.0.0/16 address space used in the homelab environment.

Network Architecture Overview

The homelab network follows a segmented architecture with dedicated subnets for different traffic types and security zones.

Network Design Principles

  1. Segmentation: Different traffic types isolated on separate VLANs
  2. Security: Management traffic separated from workload traffic
  3. Performance: Dedicated networks for storage and vMotion
  4. Scalability: Large overlay network for Kubernetes pods
  5. Flexibility: Multiple networks available for different workload types

Future Considerations

  • Phase 2: Deploy USW-Aggregation for 10G backbone
  • Phase 3: Migrate to MS-A2 hosts with native 10G networking
  • Consider additional segmentation for NSX-T requirements
  • Plan for IPv6 deployment in parallel with IPv4
