Wireless Network

The SSID is i3detroit , there is no encryption, this is considered a feature (for the moment). There is also an SSID of i3detroit-wpa with encryption; the passphrase is on posters with QR codes scattered about the space. The old SSIDs of i3 and i3test are deprecated, and they will be going away soon.

LAN Addresses

Internally, we are using the 10.13.0.0/16 supernet. It should sidestep most VPN overlap problems, should we establish any connections to other locations. At present, we are only using one subnet of this: 10.13.0.0/24.

Patch Panel

This is the page that contains the only authoritative list of what the connections on the networking patch panel go to.

Subnet: 10.13.0.0/24

Static Hosts

If you have something that needs to be attached to the network at i3Detroit, a static IP address can be assigned to it. This is useful in cases where something like a printer or a tool needs to be on the network with a known address that doesn't change.

Most member and guest laptops, however, do not need one of these.

If you have something that needs a fixed address but can't be configured for one (for some reason), something known as a DHCP reservation can be applied. Please contact Joe B or Nate W to help you out with this.
If you can, please try to create a wiki page with information about the thing you just attached to the network, and link to that from the IP address listing here.

Static hosts use the following settings:

Item Value
IP address Take an unused address from the table below. Document which address you used. When in doubt, ping first.
Subnet mask 255.255.255.0
Default Gateway 10.13.0.1
DNS Server 10.13.0.1
DNS domain name i3detroit.local
Time / NTP server 10.13.0.1 (pfSense router) or 10.13.0.5 (The LAN switch is also an NTP server)

DNS

The default DNS domain handed out for DHCP clients is i3detroit.local. If you have statically assigned a IP to something, and you want its hostname to be in DNS as your_hostname.i3detroit.local, we can add it to the local server. Post a request on the mailing list to have that taken care of.
