•
•
Model of the IP network- 20 years
DNS, DHCP, Whois data source
IP address management
Host information/inventory
Distributed administration
GNU Public License version 2 (2007)
Models how humans think of networks.
Stanford University
StanfordNetDB
DNS Name Space
• Supports domains/subdomains
• Checks all names for uniqueness
• Enforces DNS rules
– e.g. A Name cannot be MX
• Authorization of names by domain
• 1 min to generate Stanford zone file
• Updated hourly at Stanford
Stanford University
StanfordNetDB
DHCP
• Supports static/dynamic dhcp settings
• Supports DHCP options
• Updated every 10 min at Stanford
Stanford University
StanfordNetDB
IP Address Space Management
• Address spaces organized into networks
- “network” maps to layer 2 network
• Easy to split/join/move address spaces
• Authorization by address space
• Reserved addresses can only be used by gods
• Uniqueness enforced
• Automatically looks for next available address
Stanford University
StanfordNetDB
Host Inventory
• Nodes show the way humans think of
computers
• Associates nodes with people/location/dept
• Custom fields allow quick extension of
database
Stanford University
StanfordNetDB
Distributed Administration
• Ease of use allows many users
– 900+ at Stanford, 15 minutes of training
• Granular authorization
• Choice of interfaces
– Web - general users
– CLI - power users, scripting
– API - Dorms for custom interface
• Easy import/export (csv)
