Network parameters

These are the network parameters for a device on one of the Nevis networks. If a device uses DHCP, it will pick up this information automatically; you only need the following if you have to manually configure a network device.

Nevis public network

Address range = 129.236.252.0/24
Netmask = 255.255.255.0
Gateway = 129.236.252.1
Broadcast = 129.236.252.255
DNS server 1 = 129.236.252.7
DNS server 2 = 129.236.252.29
DNS server 3 = 128.59.1.3

For the mail server, use the name mail.nevis.columbia.edu; for a time (NTP) server, use time.nevis.columbia.edu. If you have to use IP addresses for that information:

Mail (SMTP) server = 129.236.252.8
Time (NTP) server = 129.236.252.7

Nevis private network

Address range = 10.44.0.0/16
Netmask = 255.255.0.0
Gateway = 10.44.0.1
Broadcast = 10.44.255.255
DNS server 1 = 10.44.7.7
DNS server 2 = 10.44.7.29
DNS server 3 = 128.59.1.3

For the mail server, use the name mail.nevis.columbia.edu; for a time (NTP) server, use time.nevis.columbia.edu. If you have to use IP addresses for that information:

Time (NTP) server = 10.44.7.7

General tips

Try to refer to a device (printer, computer, etc.) by its IP name, rather than its IP address. If you refer to 129.236.252.140 or 129.236.252.8, you may experience network problems when moving between private and public networks. If you refer to bw-research.nevis.columbia.edu or mail.nevis.columbia.edu, you won't have those problems; the Nevis DNS servers will take care of it.
