Frequently Asked Questions for Developers

  • Q: What is the CBC's Intranet topology?
    • A: The internal CBC network may contain public (but not allocated to CBC (1.0.0.0/8) addresses and private addresses, but there is no NAT between them. The server is presently on a 1.0.0.0/8 address and there is no firewall between it and the rest of the users inside CBC. The server is connected to a central router/switch where all the other subnets in the same city connect. Intercity links interconnect those router/switches in all other locations. Addresses are allocated in blocks to different cities. Here is Montreal we have 1.176.0.0/16 and in Toronto they have 1.151.0.0/16 and it goes on like this. I would have to check be I believe you can assume that if two addresses are in the same /16, that they are in the same building and or same city with high speed links.
