Networking@MIT Easy Guide
General
Registration
All new machines at MIT need to be registered in order to have full access to all MIT networked resources. This applies to both wired ethernet and wireless. To register a machine at MIT you need to go here.
Wireless Networking
Users need to connect to MIT, MIT N, MIT Secure or MIT Secure N to access MIT resources after registration. MIT Guest has no access to printer or MIT Administrative site resources.
To access MIT Secure or MIT Secure N you would type in your kerberos username and password.
Static IP Addresses for Ethernet connected machines
The one exception to the Registration rule is that any machine with assigned static IP Addresses don't need to be registered. They will work the moment they are put in. The other pieces of information you will need with a static IP Address are as follows:
Subnet Mask: 255.255.0.0
DNS Servers: 18.71.0.151, 18.70.0.160, 18.72.0.3
Please note the 18.72.0.3 has been associated with some problems resolving IP Addresses so it is best not to have this DNS server listed first or second.
DHCP for Ethernet connected machines
The way DHCP works at MIT is all unregistered machines are given an IP address in the pool 18.2.*.*
Depending on building, the pattern becomes more specific. For example, if you're Building 4, the pool is 18.2.53.*
The third number 53 is significant because this number is appropriate subnet for valid static IP Addresses. So if you had an IS&T issued static in Building 4 it would be in the 18.53.*.* subnet pool.
