Introductions• Rob Riepel
– NetDB architect– Architect/programmer/keeper for DNS, DHCP
• Dmitri Priimak– Programmer for middleware and front end
• Sunia Yang– NetDB "user advocate,” tester– Network monitoring– Application bandwidth management

What is Stanford NetDB?
• 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)
