After you select an IPv4 network container from the IPAM tab, Grid Manager displays it in the Net Map (network map) panel, by default. Net Map provides a high-level view of your IPv4 network address space. You can use Net Map to design and plan your network infrastructure, configure and manage individual networks, and evaluate their utilization. Its unique display of the IPv4 network address space across multiple rows is similar to a road map that starts with the first IP address in the network and ends with the last address. Net Map displays the network address space across a maximum of eight rows, depending on the size of the network. It automatically scales the map so that it displays the entire address space of a network container.
The Net Map panel presents a complete view of the network space, including the different types of networks that are in it and its unused address space. IP addresses that belong to a network are blocked off. Each color-coded block represents a network container, a leaf network, or a block of networks that are too small to be displayed individually in the map. For example, in a /8 or /16 network, networks smaller than /20 or /28 respectively and that are beside each other are represented as a multiple network block. In addition, the fill pattern of the blocks indicates their utilization. Therefore, you can quickly evaluate how many and what type of networks are in a network container, their relative sizes, utilization, and how much space you have left.
As you mouse over areas of the map, it displays IP information about the area. Net Map also has a zoom feature that allows you to enlarge or reduce your view of a particular area.
Figure 13.6 displays the network map of a 20.0.0.0/8 network, which is a network container that has network containers and leaf networks.

Displaying IP Information
As shown in Figure 13.6, as you mouse over the map, Net Map displays IP information about the area. When you mouse over an unused area, Net Map displays the following information:
