DRAFT
BCWARN IP Numbering Specification
Jeremy Cohoe
26-DEC-2005
Variables and explanation of terms
IP addresses follow the a.b.c.d format with each variable between 1 and 255
There are 4 classes of IP subnets, A, B, C, D.
Class A - 16,581,375 (255x255x255)
Class B - 65,025 (255x255)
Class C - 255
(see ref)
For each site there will be one class C (255) Ip addresses available, eg: x.x.x.1-255
Once a device leaves a site it's IP should be updated to reflect the new site ID.
The class A subnet used by BCWARN still needs to be decided upon. Ideally, the IP designated by the ARIN/ICANN for use for Amateur Radio will be used. Failing that, BCWARN will use the 10.x.x.x internal subnet for all IP addresses.
Routes will be setup on the main Firewall/NAT box or device.
Examples:
10.1.1.1 Main Firewall at the ROOT location (Currently SFU)
10.1.2.1 Main firewall at location 2 (NWARC)
10.1.3.1 Main firewall at location 3 (Coquitlam ARC)
10.1.4.1 Main firewall at location 4 (Saltspring Island)
etc
Each main firewall will be set with at least one gateway/route. One additional gateway will be set so that all outbound IP traffic destined for the internet will get routed through their local internet gateway (Shaw cable/telus ADSL internet, etc). The gateway for all BCWARN traffic will be an IP address on the Main firewall at the root location.
Each device on the SITE network/subnet will have a single gateway of 10.1.X.1, where X is the site ID.
The route for that device will be determined by the router.
The subnet mask will only need to be 255.255.255.0.
The subnet mask of the router will be wider than 255.255.255.0 so that the router at the site can contact the main router at the root node.
The root node will have pre-determined routes setup for each site.
Site 1 is the root node.
Site 2 will have a gateway of 10.1.1.102
Site 3 will have a gateway of 10.1.1.103
Site 4 will have a gateway of 10.1.1.104
etc.
