Contact Roles in NetReg register or claim network assets. Network assets include subnets as defined by the network group, IP addresses, subdomains, off-site hostnames, and eventually individual devices and restricted data systems.
As defined by NOS, either IPv4 or IPv6. NOS allocates subnets. Contact roles claim subnets (also known as CIDR blocks) for the purpose of obtaining security notices involving those IP addresses.
Individual IP addresses (IPv4 only) can also be registered to Contact Roles. They are requested and transferred among Contact roles. This applies only to IPv4 as IPv6 address space will not be subdivided beyond NOS assigned CIDR blocks within NetReg.
Contact roles may also register subdomains in order to facilitate finding, requesting and transferring individual IP addresses.
Registered subdomains are also used to facilitate self-registration of Fixed DHCP address registrations with automatically generated DNS hostnames (e.g., fixed-nnn-nnn-nnn-nnn.subdomain.berkeley.edu).
Off Site Hostnames:
Contact roles must register off-site hostnames for the purposes of scanning, incident tracking and notification.
Devices (aka Ethernet MAC addresses) are registered for the purpose of using the campus DHCP service and to obtain security notices involving those devices.
University owned devices should be registered by the Department (or Group) Security Contact. Personally owned devices can be registered by using your Individual Contact Role context.
