Status Idea

The 57North Hacklab Network will provide all the necessary components to connect our hackers to the public Internet using both IPv4 and IPv6 and also to the ChaosVPN, dn42 and Freifunk networks.

Networks

When considering new IP ranges, it is necessary to consider which ranges would already be in use in ChaosVPN, dn42 and Freifunk. The range 192.168.0.0/16 is available for local use and not routed outside the hackerspace. For IPv6, the hackerspace has a global scope address block (2001:470:510b::/48), from Hurricane Electric, and this surfaces in Germany.

VLAN Description Address Range IPv6
DMZ DMZ 89.104.228.104/29 (none)
100 Wired LAN 172.31.4.0/24 2001:470:510b:4::/64
110 Wireless LAN 172.31.5.0/24 2001:470:510b:5::/64
120 Spare Network (Reserved for future use) 172.31.6.0/24 2001:470:510b:6::/64
130 Spare Network (Reserved for future use) 172.31.7.0/24 2001:470:510b:7::/64
140 Door Access 89.104.228.106 (none)

IPX support is planned, but will need to happen later due to time constraints. Ideas include just routing IPX over our wired/wireless VLANs but then also between hackerspaces over ChaosVPN.

Network Rack

The network rack is the top, wall mounted rack.

It floats, as if by magic.

ChaosVPN

ChaosVPN is a VPN to connect hackers and hackerspaces. The wired and wireless LANs are connected to ChaosVPN and, via ChaosVPN, dn42 and Freifunk's networks.
