Getting Started


NetReg uses different kinds of security contact roles (CRs) to support the different ways network resources are managed on campus.

Network assets (e.g., subnets, IP addresses, devices) are registered to CRs in NetReg to enable correct routing of security notices.  A CR is comprised of members, NetReg system users who have been authorized for membership and have various levels of access privileges. 

CR members can have the ability to:

  • View and respond to NetReg messages
  • View and edit registration of IP address space and DNS subdomains
  • Register DNS hostnames for off-site hosts
  • Register devices for DHCP services

There are several types of contact roles, each corresponding to a specific purpose - there are contact roles for department security contacts, sub-department or "group" security roles, individuals, and service providers.

NetReg provides a means of creating new CRs, and administering CR membership, as well as tools for registering network resources.

Contact Roles

NetReg is a role-based system.  Network assets are registered to a security contact role, and authorized members of the role can perform registration functions.  There are 3 main types of roles.

Individual Contact Role (ICR)

Every user in NetReg has an ICR, specific only to that user.  It is used for requesting membership to Department or Group Contact Roles, and for registering personally owned devices for DHCP services.

Department Contact Role (DCR)

Members of a DCR manage network asset registration for an organization or department within the university. 

Group Contact Role (GCR)

Group Contact Roles (GCRs) are created by DCRs when a separation of responsibility is necessary.

Both GCRs and DCRs have the same functionality within NetReg.  They can claim, request, and transfer IP address space and register other network assets.  See the "Contact Roles" documentation for more detailed information.

Logging into NetReg

To log in to NetReg, go to the NetReg Home Page and select the "Login" button.  Use your CalNet ID and passphrase to authenticate:

Once logged in, select a security contact role for this session - use the drop down list to choose a Contact Role.

 Select context.  Select the Contact Role to use for this session.

Your Individual Contact Role (ICR) gets created the first time you log in. If you are already a member of one or more security contact roles for your department or unit, these roles will appear in the drop down list.

If you would like to switch roles at any time, use the "Select Context" option from the left navigation menu.

Note:  The "Help" menu provides page-content related documentation on each page.
