NetBox - IP Address Management (IPAM) and Data Center Infrastructure Management (DCIM) Tool

Monday, July 4, 2016

NetBox is an IP address management (IPAM) and data center infrastructure management (DCIM) tool. Initially conceived by the network engineering team at DigitalOcean , NetBox was developed specifically to address the needs of network and infrastructure engineers.

NetBox runs as a web application atop the Django Python framework with a PostgreSQL database. For a complete list of requirements, see requirements.txt . The code is available on GitHub .

NetBox understands all of the physical and logical building blocks that comprise network infrastructure, and the manners in which they are all related.

DCIM comprises all the physical installations and connections which comprise a network. NetBox tracks where devices are installed, as well as their individual power, console, and network connections.
Site: A physical location (typically a building) where network devices are installed. Devices in different sites cannot be directly connected to one another.
Rack: An equipment rack into which devices are installed. Each rack belongs to a site.
Device: Any type of rack-mounted device. For example, routers, switches, servers, console servers, PDUs, etc. 0U (non-rack-mounted) devices are supported.

IPAM deals with the IP addressing and VLANs in use on a network. NetBox makes a distinction between IP prefixes (networks) and individual IP addresses.
Because NetBox is a combined DCIM/IPAM system, IP addresses can be assigned to device interfaces in the application just as they are in the real world.
Aggregate: A top-level aggregate of IP address space; for example, or 2001:db8::/32. Each aggregate belongs to a regional Internet registry (RIR) like ARIN or RIPE, or to an authoritative standard such as RFC 1918.
VRF: A virtual routing table. VRF support is currently still under development.
Prefix: An IPv4 or IPv6 network. A prefix can be assigned to a VRF; if not, it is considered to belong to the global table. Prefixes are grouped by aggregates automatically and can optionally be assigned to sites.
IP Address: An individual IPv4 or IPv6 address (with CIDR mask). IP address can be assigned to device interfaces.
VLAN: VLANs are assigned to sites, and can optionally have one or more IP prefixes assigned to them. VLAN IDs are unique only within the scope of a site.

Long-distance data connections are typically referred to as circuits . NetBox provides a method for managing circuits and their providers. Individual circuits can be terminated to device interfaces.
Provider: An entity to which a network connects to. This can be a transit provider, peer, or some other organization.
Circuit: A data circuit which connects to a provider. The local end of a circuit can be assigned to a device interface.

NetBox provides encrypted storage of sensitive data it calls secrets . Each user may be issued an encryption key with which stored secrets can be retrieved.
Note that NetBox does not merely hash secrets, a function which is only useful for validation. It employs fully reversible AES-256 encryption so that secret data can be retrieved and consumed by other services.
Secrets Any piece of confidential data which must be retrievable. For example: passwords, SNMP communities, RADIUS shared secrets, etc.
User Key: An individual user's encrypted copy of the master key, which can be used to retrieve secret data.
