 * Networks - one client's, or every network the agent can see from All Client
 * Docs. Each row is a subnet: what it is for (its type, as the tile), the
 * CIDR, VLAN and gateway, the DHCP range, the site, and how full it is - the
 * addresses documented on it and on the devices set to it, against its size -
 * with an amber edge when its address plan has a problem (two devices on one
 * address, a fixed address inside the DHCP range, a device outside the
 * subnet). The pills along the top split them by type.
 *
 * Searching for an address finds the networks it is in - 192.168.10.57 finds
 * the 192.168.10.0/24 networks - and the networks it is documented on.
