Mill Network - VLAN '1'

The mill provides internet access via a 100mbps internal network. It can be a bit unreliable but it works for our general usage.

ISP: Awareness Software Ltd (AS34931)
Mill Network Administrator: Mark Nightingale, Image Village.

Access to the mill network is provided by a singular CAT5 delivered to the rear of the main space, just above where Rack 1 is.

VLAN: 1 (untagged)
Subnet: 192.168.20.0/24
Gateway: 192.168.20.1
DHCP Enabled

Usage is bound by the LBPT Tenant Network Agreement.

Shared Services - VLAN 225

Where the servers, routers, and other central bits are hosted.

IP Range: 10.3.1.0/24

The range is split into logical groups:

1 to 9 - Network hardware
10 to 19 - Physical Servers
20 to 29 - Physical Server Management Interfaces
30 to 49 - VMs
50 to 59 - Printers

This subnet does have DHCP enabled, but we encourage static assignments for critical hardware and services. Here is the current list:

Device Name	IP Address	Location
GW	`10.3.1.1`	Rack 1
Switch 1	`10.3.1.2`	Rack 1

GW - VIP 2	`10.3.1.61`	VIP for K8s-Lab

WiFi - VLAN 226

WiFi users, General open access to the internet and internal services. The UnFi APs management interface is in Shared Services on DHCP, only non-UnFi devices are assigned a static IP on the WiFi VLAN.

IP Range: 10.3.2.0/24

DHCP enabled, 10.3.2.21 - 10.3.2.254

Device Name	IP Address	Location
AP4	`10.3.2.5`	Behind Rack 1
Cam1	`10.3.2.6`	Rack 1
Cam2	`10.3.2.7`	Defunct
Cam3	`10.3.2.8`	Social Space
Cam4	`10.3.2.9`	Main Space
Cam5	`10.3.2.10`	Pi Room
Cam6	`10.3.2.11`	Workshop
Cam7	`10.3.2.12`	CNC

Device	2.4ghz	5ghz	6ghz
AP1	Auto	Auto	N/A
AP2	Auto	Auto	N/A
AP3	Auto	Auto	N/A
AP4	13	N/A	N/A

Wired - VLAN 227

The general hackspace wired network. This covers the Pi Room, Classroom, Electronics, and Fabrication.

IP Range: 10.3.14.0/24

DHCP enabled, 10.3.14.2 - 10.3.14.254

Automation - VLAN 229

Used for any automation devices that do not require open internet access, or need to be secured away from the general network (e.g. Door system).

Accessible via Leighhack-iot WiFi SSID.

IP Range 10.3.16.0/24

DHCP enabled, 10.3.16.2 - 10.3.16.128

This subnet does have DHCP enabled, but we use some static assignment. Here is the current list:

Device Name	IP Address	Location

DMZ - VLAN 230

Used for internet facing services, all systems are allocated addresses within the A&A delegated IP range.

IP Range: 81.187.195.16/29

Device Name	IP Address	Location
GW	`81.187.195.17`	Rack 1

Storage - VLAN 231

Non-routed VLAN for VM hosts to connect to storage devices either via iSCSI or NFS, to keep that main broadcast traffic off the main subnets.

Currently not implemented

IP Range: 10.254.254.0/24

Device Name	IP Address	Location
`nas02`	`10.254.254.2`
`monster1`	`10.254.254.11`
`monster2`	`10.254.254.12`
`monster3`	`10.254.254.13`
`monster4`	`10.254.254.14`
`monster5`	`10.254.254.15`

AD Lab - VLAN 232

IP Range: 192.168.10.0/24

A non-routed VLAN for our Active Directory lab - GOAD

Consult the GOAD documentation for the breakdown of systems within the environment.

OpenVPN

The pfSense has a OpenVPN server, this allocates IPs in the 10.3.254.0/24 range and is available as a normal interface on pfSense, but it doesn't have a VLAN assigned to it.

OOB Access

Out of band access to the network is available via 'Leigh OOB', this uses Tailscale to handle situations where GW or the L2TP is unavailable.

For access, contact the Infra team, or Andrew Williams.
