-For large networks the task of maintaining the total IP address scope may be a challenge in itself. It is useful to have an overview of all the subnets in operation, and whats more, how full they are, i.e. how many machines ​do they contain. NAV introduces a tabular view that gives an excellent overview on a single page:+For large networks the task of maintaining the total IP address scope may be a challenge in itself. It is useful to have an overview of all the subnets in operation, and what is more, how full they are, i.e. how many machines they contain. NAV introduces a tabular view that gives an excellent overview on a single page:

 +A prerequisite for this tool to work is that you have seeded your database with one or more scope prefixes. The scope prefixes defines your total address room. You may have both IPv4 and IPv4 scopes. Each scope can be visualized as shown in the example.
 +
 +You may also use the reserved prefix option in Seed Database. A reserved prefix is a prefix that is allocated for a purpose, but is not yet in production. For more info on registering scope and reserved prefixes [[seedessentials#​prefix|see here]].
 +
 +A brief explanation of the functionality in the prefix matrix:
 +
 +  * Layout
 +    * For IPv4 each row is a /24 scope and the columns counts from 0-255
 +    * For IPv6... (to be completed)
 +  * A coloured area means that this prefix is in use or allocated
 +    * reserved prefixes are brown
 +    * in cases where there are many small subnets (meaning too small to display in a good manner), the row is blue
 +    * prefixes in use follow a colour scheme based on their utilization rate: 
 +      * a very heavily used prefix will be red
 +      * a lightly used prefix will have a light colour
 +  * The displayed percentage is the actual percentage of the IP addresses in the prefix that are in use. If you click on this link you will be directed to the machine tracker that can display the actual IP addresses (and mac addresses) that are in use.
 +  * If you click on the row titles on the left you will be directed to a report displaying all prefixes in that area
 +  * If you click on an actual allocated prefix you will e directed to a report displaying details regarding this prefixes ​
 +  * If you uncheck the "Show unused address rows" you will get a collapsed view removing rows where there are no allocations.
