This is an old revision of the document!
This document reflects the current status of the network at Vegagatan 1.
The network will be segmented in various VLANs to separate the different associations in the local. Also separation between wireless and cabled networks will be done to keep their broadcast domains separated.
The following is the current assignment:
|10||Administrative VLAN||Network equipment administration and synchronization|
|20||Services VLAN||Intranet services|
|40||GHS||Wired LAN and WLAN for the Göteborg Hackerspace|
|50||Others||WLAN for the other associations|
|60||Guest Cable||Wired LAN used in the connected outlets expect Hackerspace ones|
|70||Guest Wifi||WLAN for Guests coming to the local|
IPv4 addressing is done using the 10.0.0/8 network. We'll use the VLAN identifier as the second digit and leave the other two digits for host addresses. The subnets 10.x.1.0/24 and 10.x.255.0/24 are always reserved for static address use (not to confuse with static DHCP reservations).
The router always has 10.x.0.1 as address, the other reserved addresses are currently:
|10.10.0.2||Core switch||Panic Room|
|10.10.0.3||Access Point 1||Near Cykel Köket|
|10.10.0.4||Access Point 2||Over Hackerspace tables|
|10.10.0.5||Access Point 3||In the Conference Room|
We are using Hurricane Electric's IPv6 tunnels to provide IPv6 addresses on our network. The subnetwork assignments are as follows:
|2001:470:27:23f::/64||Hurricane electric Tunnel|
|2001:470:dc07::/48||VLAN Assignments (see below)|
The mapping of the /48 to VLANs is similar to the one done with the 10.0.0.0/8 network. The next 16 bits are assigned to the VLAN number written directly in hexadecimal.
The mapping of devices is similar to the one done with IPv4, the DHCP addresses and SLAAC addresses are given from the corresponding pool (::1:0-::1:ffff for DHCPv6). The ::1 and ::ff networks are reserved for static assignments on the 10.x.255.y and 10.x.0.y parts of the network. But with the last octet expressed in decimal to simplify the reading.
Also the router will always be assigned the ::1 address of the network.
As of now IPv6 will only be deployed unfiltered on the hackerspace network and filtered on our internal VLANS (administrative and services).
If you want to disable ipv6 on linux just run your kernel with the ipv6.disable=1 parameter
