current configuration
------------------------------------------------

T1 (from library, subject to e-rate restrictions, configuration not to be changed)

DSL
  o Verizon
  |-> Linksys BEFSR41 router
    o 192.168.50.1
    o DHCP 192.168.50.[100-]
    o subnet: 255.255.255.0
    |-> Netgear 24 (24x)
    |-> Cisco EZXS88W switch (classroom)
    |-> Linksys EF4116 switch (fab lab)
    |-> static IP address
        o Minolta copier: 192.168.50.10
        o IBM printer: 1928.168.50.11
        o network camera: 192.168.50.30
        o HP printer/scanner: 192.168.50.89
        o laser cutter: 192.168.50.90
        o Roland maker: 192.168.50.91
        o Modella: 192.168.50.92

Comcast
  o 3 mbit down
  o 512k up
  |-> Cisco UBR905
  IP addresses 65.96.109.89 thru 93 (see below for used ones)
    o Cisco 1721 router is attached to UBR905 and is using 65.96.109.90, 192.168.100.1
        that router hands out addresses in the 192.168.100.x range
    (The UBR905 router also would do dhcp in the 192.168.100.x range)
    Attached to Cisco 1721 router is Cisco 2924 switch (not as of now)
    o gateway: 65.96.109.94
    o subnet: 255.255.255.0 (internal LAN) 255.255.255.248 (Comcast)
    o Attached to one Cisco 2924 switch port is a Cisco Aironet 1100 (wireless) access point providing WiFi for lab (switch is disconnected)
    o An ethernet cable connects to a Hawking switch on the roof.
    o Web requests to port 80 of 65.96.109.90 are forwarded to one of the access points on the roof
    |-> Mac Xserve (streaming server)
       o Xserve IP address: 65.96.109.89
