Backhaul Subnet Allocations

The thirty-two 10.12.0.0/29 subnets are used for backhaul links within our various networks. This page is for tracking their allocation and other useful details.

Why We Have These

Our networks are generally routed networks of individual subnets rather than bridged networks. This is in large part because few of the wireless card drivers we use allow bridging directly between two wireless cards. Thus it is often necessary to have a couple of IP addresses to link between two nodes. Rather than take a large IP address space (e.g. a /24 containing up 252 addresses) we use smaller /29 subnets that allow 6 IPs. Most of the time we only need two IPs, but occaisionally we need more (e.g. a point to multi-point link, or a management IP) so we went with the slightly larger space.
