Primary IT Infrastructure

Please check back with this page, as we are in the process of populating good information, relating to how to get the most out of your HackRVA data experience.

The primary network architecture

At HackRVA Labs, Inc. we utilize a switched network with vlans and VoIP support. We have a dedicated smart-switch, a router and a Virtulization Server which runs our web services, and groupware.

Network Devices

The HackRVA Labs, Inc. network is comprised of four primary network infrastructure devices.

CPE devices

MOTOROLA Surfboard Cable Modem

The previously used DOCSIS 3.0 cable modem used at the space was a MOTOROLA SB6120.
This device does not allow for provisioning of static IPv4 addresses, hence the use of the SMC Business Gateway for our current level of service.

SMC Business Gateway

HackRVA Labs, Inc. uses comcast business class service with static IPv4 provisioned
The device provided for this service is the SMC Networks SMCD3GCCR business gateway.
The device provides a four port switch, for easy integration into our network architecture.

Cisco RV180 VPN Router

The RV180 VLAN-enabled VPN SOHO router is the brains of the internal network architecture.
This device provides dhcp to clients on the internal LAN as well as NAT functionlaty for accessing the internet from behind the cable modem.
To understand what vlan capabilities are being used as the space, please reference the VLAN section, below.

NetGear 24-port smart-switch

This device is referenced by Netgear as the GS724T-300 smart-switch.
This device is capable of vlan tagged ports, as well as port trunking.

Network Topology

VLANs

At HackRVA Labs, Inc. we have a segmented network using vlans for segregation of traffic.

• VLAN-1 is the management network, and houses the management end-points for primary services.
• VLAN-100 is the voip vlan, specifically intended to have all voip traffic.
• VLAN-200 is the vlan for hackrva-wireless, and is the vlan which you will be assigned to, if access the hackrva-wireless ssid.
• VLAN-300 is the vlan for all wired network infrastructure, and is also the vlan for network services such as email, and dns, as well as network printers.

Address Space (IPv4)

At HackRVA Labs, Inc. we have subneting that is assigned to specific vlans.

• VLAN-1 is on subnet 192.168.10.0/24
• VLAN-100 is on subnet 192.168.100.0/24
• VLAN-200 is on subnet 192.168.200.0/24
• VLAN-300 is on subnet 192.168.30.0/24

Address Space (IPv6)

HackRVA Labs, Inc. does not currently utilize IPv6 address space.
