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:

  • View and respond to NetReg messages
  • Register subnets and IP addresses
  • Register web service off-site hostnames
  • Register devices for DHCP services
  • Register RD Applications
  • Make changes to a security contact profile or membership.

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

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

Security Contacts

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

Individual Security Contact (ISC)

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

Department Security Contact (DSC)

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

Group Security Contact (GSC)

GSCs are created by DSCs when a separation of responsibility is necessary.

Both GSCs and DSCs have the same functionality within NetReg.  They can claim, request, and transfer IP address space and register other network assets.  See the "security contacts" 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 for this session - use the drop-down list to choose a security contact.

 Select Context


Your Individual security contact (ISC) gets created the first time you log in. If you are already a member of one or more security security contacts 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.
