Looking for an application which can hold the data of all the servers you maintain? You might have found it.
This Qt-application makes it possible to add hosts and store info about them. You can choose which info you want.
If you want to store IP-addresses, you enter a key 'ipv4' and as value '192.168.100.1'. You will then get an extra tab called 'ipv4' which lists all hosts for which you have set this property. The property names are free, you can choose them, so you can use 'OS','XEN-Host' or whatever way you want to organise your hosts.
