Leela runs the standard Debian package of BIND 9, which is at the time of writing 9.2.3+9.2.4-rc5-1.
The named daemon on leela is responsible for both dealing with and forwarding local requests, and answering authoritatively external requests for the tardis.ed.ac.uk domain.
The DNS philosophy of tardis is to use the machines' own names for A records and have as many CNAME's as necessary as aliases for their functions, i.e. ssh.tardis.ed.ac.uk is a CNAME for gallifrey.
The addresses in the tardis domain are distributed thusly:
- 1 Default VLAN (Infrastructure) 192.168.1.0/24
- 2 Internal Network 192.168.0.0/27
- 3 External Services 193.62.81.0/27
- 4 External Sandboxes 193.62.81.32/28 (aka Solaris Machines/Containers)
- 5 Gamesoc 193.62.81.48/29
- 6 Laptops 193.62.81.56/29
