Campus Residence Access (ResNet)

ResNet is the University of Toronto Residence Network, which provides Internet access to students in residence. If you are having technical problems with this network, please contact your residence's IT support.

Note: The Information Commons Help Desk does not provide support for ResNet.


You will need to set your computer up on ResNet and pass a security check before you will be allowed to use it to access to the internet. The University residences normally provide detailed information to you when you sign in. If you need assistance, please contact your residence's IT support.

Using ResNet

Can I use my own IP address in the University Residence?

No. All traffic originating within the University Residence subnets is filtered at the local router interface to ensure that the source address is within that subnet's assigned address range. This filter prevents IP source address spoofing, which is commonly used during denial-of-service attacks to mask the actual source of the attack.

What restrictions are there on sending emails in Residence?

To prevent systems from propagating malware such as viruses, spyware and Trojans (which often have self-contained SMTP agents), or acting as spam relays (often as part of a 'botnet'), SMTP (TCP port 25) is blocked outbound at the residence connection to the campus backbone.

You will need to set your computer up on ResNet before you will be allowed access to the internet, the University residences normally provide this information to you when you sign in.

Each college at U of T has its own policies regarding ResNet, For information specific to your college, please visit the corresponding site below:
