## Overlap Analysis
|
|
|
|
### ✅ **NO OVERLAPS DETECTED**
|
|
|
|
All sites use different /20 management subnets within the 10.10.0.0/16 range:
|
|
|
|
1. **10.10.16.0/20** - Climax
|
|
2. **10.10.48.0/20** - 982 Site
|
|
3. **10.10.64.0/20** - 380 Core

7. **10.10.160.0/20** - 494 Site
|
|
|
|
## Key Observations
|
|
|
|
1. **Consistent Subnet Size**: All management networks use /20 subnets (4,096 addresses each)
|
|
2. **Sequential Allocation**: The subnets appear to be allocated sequentially within the 10.10.0.0/16 space
|
|
3. **Common VLAN**: Most sites use VLAN 10 for management traffic
|
|
4. **No Conflicts**: Each site has its own unique management subnet with no overlaps
|
|
|
