Getting Started


NetReg uses distinct sets of security contacts (SCs) to support the various ways network resources are managed on campus.

Network assets (e.g., subnets, IP addresses, devices) are registered to SCs in NetReg to enable the correct routing of security notices.  An SC is a role that is comprised of members. NetReg users who have membership in a security contact have varying levels of access privileges.

SC members may have the ability to:

Initially, security contacts and their maintainers, as well as registered IP addresses and subnets, subdomains and off-site hostnames were converted from the previous Security Contact application.

For new registrations and ongoing maintenance of existing registrations:

How are security notices routed?

Security notices are routed based upon the most specific registration information available in NetReg.

For example, if an IP address has a registered security contact, the security notice is sent to that contact. If there is no specific IP address registration then the notice is sent to the security contact that claimed the subnet. Notices will also be sent to:

•    the registrant contact role's service provider if any
•    its departmental / parent contact role if any,
•    and any contact roles that have 'CC SC' status for the IP address

What are Service Provider Security Contacts and how do they work?

Service Provider Security Contacts (SCs) are a special purpose security contact.  As a service provider, they don't have registered network assets, but they are flagged within NetReg as providing support for another SC.  For example, the Service Provider SC might register devices for the Client SC. Service Provider SCs have "device-based" privileges with the Client SC; they can create, edit and delete devices from the Client SC.

Privilege Levels for Security Contact Members

Security Contact Privilege Levels

Security Contact roles can have one of the following privilege levels:   View-only, Device, IP Information, and Admin


Security Contacts with ‘View-Only’ privilege level can view registered assets, but not alter or make changes to them.


Security Contacts with ‘Device’ privilege level can add or edit device registrations.

I've received an "IP address to transfer" message.

Here we explain what it means and what you need to do.

You've received the message because Netreg has encountered a mismatch between the security contact that claimed an IP address (individually or by subnet) and the security contact that registered a subdomain.

(Note: In Netreg the assignment of a subdomain enables the transfer of IP address responsibility to the right party, but does not assign security contact responsibility).
