Network IP Allocations

This page is the master IP allocation list for SoCalFreeNet networks. Per the master list at FreeNetworks, we have reserved the 10.12/16 subnet. We typically use a class C (/27) subnet at each new physical location which allows for 30 computers.

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.

Golden Hill Network Allocations

The following are the subnets and various hardware info for the Golden Hill network. It is currently incomplete.

Subnet 10.12.2.0/27 - K26 (924 26th Street)

This installation uses the 10.12.2.0/27 subnet - i.e. 10.12.2.0 to 10.12.2.31. This is further divided as follows:

A Netgate PowerG8 is used as the main AP, running m0n0wall. The three ports are assigned as follows:

This small subnet hooks the La Cresta 802.11a backhaul to Pink Palace to the 802.11a radio that services 27th and Broadway and soon also K26. The 'a' radio runs in bridged mode to avoid another subnet and for simplicity.

Mercado network IP addresses

Mercado Network IP Information

The Mercado network consists of a master node and subnodes. Each subnode consists of an 802.11a relay radio and an 802.11b local AP radio. Each subnode has its own independent subnet and runs its own dhcp server and DNS cache. This allows easier location of problem clients (they can be readily identified by IP).

Each subnode works in a 32 address subnet and follows the same
general layout:

SettingValue

CIDR / length/27
802.11b radiofirst address in range
eth0 portsecond address in range
802.11a radioaddress from master node subnet
DHCPall unused addresses are allocated

The subnets are allocated from the range 10.12.12.x as shown
