IAC Network Configurations

Networks with IAC computers

ISU

All ISU machines (including private networks) use the DNS servers of 134.50.254.5 and 134.50.57.57

IAC/PSI

• "real" ip addresses are 134.50.87.x
  • gateway 134.50.87.254, netmask 255.255.255.0
• NAT router address 134.50.87.12, 134.50.87.11, 192.168.1.1
  • NAT ip config: range 192.168.x.x, gateway 192.168.1.1, netmask 255.255.0.0
  • 192.168.87.x addresses are reserved for machines that have a reserved 134.50.87.x address
• dhcp addresses are in range 192.168.40.x

Physics

• ip addresses are 134.50.3.x or 134.50.203.x
  • gateway 134.50.3.254 or 134.50.203.254 (as appropriate)
• static addresses are only in 134.50.3.x range, dhcp addresses span both

Biology

• ip addresses are 134.50.65.x or 134.50.165.x
  • gateway 134.50.65.254 or 134.50.165.254 (as appropriate)
• No dhcp

Airport

• dhcp
• wired and wireless (same WEP as IAC)
• not connected to ISU's network

Private Networks

Brems

• ip addresses 10.0.x.x/255.255.0.0
  • gateway 10.0.200.1
  • dhcp range 10.0.0.100-10.0.0.150
• static dhcp assignments pinned to MAC addresses
  • Brems nodes 10.0.200.x
  • Inca boot (100mbit) 10.0.2.x
  • Inca cluster (gigabit) 10.0.100.x

Mail Servers

• Outside IP addresses are taken over by the other machine in the event of failure
  • Newton outside 134.50.3.194
  • Darwin outside 134.50.3.195
• Private network (crossover cable) for syncing and heartbeat 10.2.2.x/255.255.255.0
  • Newton private 10.194.0.1
  • Darwin private 10.194.0.2
