Restructure docs: archive VLAN migration, update IPs to VLAN 10 
Major documentation cleanup after VLAN migration completion:
- Archive 12 VLAN project docs to archive/vlan-migration/
- Archive 5 done WIP docs (VLAN proposals, AI stack, Fossorial, DNS backup)
- Create standing reference docs 08-DNS-ARCHITECTURE and 09-TAILSCALE-VPN
- Renumber docs to clean 01-09 sequence with merged CHANGELOG
- Update all active docs from stale 192.168.31.x to current VLAN 10 IPs
- Fix CSS1 (.10.9→.10.3) and ZX1 (.10.7→.10.4) IPs in hardware inventory
- Clean 06-VLAN-DEVICE-ASSIGNMENT: remove migration columns/sections, fix VLAN 25 subnet

# WIP: VLAN Network Segmentation Proposal
**Status:** Planning
**Created:** 2026-01-25
**Updated:** 2026-01-25
---
## Decisions Made
- ✅ Separate Camera VLAN (VLAN 35)
- ✅ Guest WiFi: Password only (no captive portal)
- ✅ Keep 192.168.31.0/24 during transition (VLAN 1)
---
## Current State
Single flat network: `192.168.31.0/24` (will become transition VLAN)
---
## Proposed VLAN Architecture

## MikroTik Implementation
### 1. Create VLANs
```routeros
/interface vlan
add interface=bridge name=vlan10-mgmt vlan-id=10
add interface=bridge name=vlan20-trusted vlan-id=20
add interface=bridge name=vlan30-iot vlan-id=30
add interface=bridge name=vlan35-cameras vlan-id=35
add interface=bridge name=vlan40-servers vlan-id=40
add interface=bridge name=vlan50-guest vlan-id=50
```
### 2. IP Addresses
```routeros
/ip address
add address=192.168.10.1/24 interface=vlan10-mgmt
add address=192.168.20.1/24 interface=vlan20-trusted
add address=192.168.30.1/24 interface=vlan30-iot
add address=192.168.35.1/24 interface=vlan35-cameras
add address=192.168.40.1/24 interface=vlan40-servers
add address=192.168.50.1/24 interface=vlan50-guest
```
### 3. DHCP Pools
```routeros
/ip pool
add name=pool-trusted ranges=192.168.20.100-192.168.20.220
add name=pool-iot ranges=192.168.30.100-192.168.30.220
add name=pool-cameras ranges=192.168.35.100-192.168.35.140
add name=pool-servers ranges=192.168.40.100-192.168.40.150
add name=pool-guest ranges=192.168.50.100-192.168.50.200
```
### 4. Camera Geo-Blocking
```routeros
/ip firewall address-list
add list=blocked-countries address=0.0.0.0/8 comment="CN/RU blocks - add actual ranges"
/ip firewall filter
add chain=forward action=drop src-address=192.168.35.0/24 dst-address-list=blocked-countries
```

## Migration Plan
### Phase 1: Preparation (No Downtime)
- [ ] Document all static IPs and MAC addresses
- [ ] Create device inventory with target VLANs
- [ ] Configure VLANs on MikroTik (inactive)
- [ ] Configure switch trunk ports
- [ ] Test on isolated port
### Phase 2: Infrastructure (Brief Downtime)
- [ ] Create VLAN interfaces and IPs
- [ ] Configure DHCP per VLAN
- [ ] Move Unraid management to VLAN 10
- [ ] Move AdGuard to VLAN 40
- [ ] Update container networks
### Phase 3: WiFi (Rolling)
- [ ] Create new SSIDs per VLAN
- [ ] Move personal devices to VLAN 20
- [ ] Move IoT devices to VLAN 30
- [ ] Test mDNS/Bonjour relay
### Phase 4: Cameras & Security
- [ ] Move cameras to VLAN 35
- [ ] Implement geo-blocking
- [ ] Test camera isolation
- [ ] Verify Trusted can view feeds
### Phase 5: Cleanup
- [ ] Implement all firewall rules
- [ ] Enable DNS enforcement
- [ ] Migrate remaining devices from VLAN 1
- [ ] Document final configuration
- [ ] Deprecate VLAN 1 (keep for emergency)
---
## Rollback Plan
If issues occur:
1. All devices can temporarily use VLAN 1 (legacy)
2. MikroTik remains accessible on 192.168.31.1
3. Keep VLAN 1 DHCP active during transition
