Network Infrastructure
- The BSOE network (cse.ucsc.edu and soe.ucsc.edu domains) supports more than 650 funded network connections
- Switched 100Mbs service to the desktop
- Selected hosts provided 1Gbs access
- BSOE maintains a gigabit uplink to the ucsc.edu network
Important IP addresses for self-maintained machines
For those who maintain their own systems and are not using DHCP, the following are the magic IP addresses for the various networks in the SOE.
DNS Servers
We recommend using this as a resolv.conf file:
domain cse.ucsc.edu
search cse.ucsc.edu ucsc.edu
nameserver 128.114.48.21
nameserver 128.114.48.22
nameserver 128.114.48.23
(Note: If you run IRIX, please contact to determine if you also need a hostresorder line.)
NTP Servers
Please see Gary's writeup on the correct NTP settings.
Default Routers and Subnet Masks
Depending on the network you are on, the following are the correct default routers for that network. You must also correctly set the subnet mask. If you do not see an entry for the network you are on, we do not support that network and you should contact the provider of that network.
| Subnet Range | Subnet Mask | Default Router | Comment |
|---|---|---|---|
| 128.114.48.1 - 128.114.55.254 | 255.255.248.0 | 128.114.48.1 | Primary SOE Net |
| 128.114.62.1 - 128.114.62.254 | 255.255.255.0 | 128.114.62.253 | SOE Instructional Net |
| 128.114.63.1 - 128.114.63.254 | 255.255.255.0 | 128.114.63.253 | SOE Research Net |
WINS Server Addresses
If you run Windows and need to use Microsoft Networking you will need to enter the WINS servers. They are:
128.114.48.40
128.114.48.41
Windows or Mac users should consider DHCP or plug-in the various values in the correct Control Panel->Network area.
