Hello, i need to introduce a new IP V4 Table into the current release of the ripe-db software for a local project at Cable&Wireles. The best starting point for impletenting this is probably the definition of the current ipv4 definition of "inetnum" in attributes.xml. Befor i go ahead and start reading through tons of sourcecode, especially the one used for radix-tree operations, i thought i might ask here if someone has any general tips on what to change/not to change. Comment on the current definition if the inetnum object would also be of great help to me. I.e. which attributes to copy and which need to be changed etc. best regards, Arnd Vehling -- NetHead Network Design and Security Arnd Vehling av@nethead.De Gummersbacherstr. 27 Phone: +49 221 8809210 50679 Köln Fax : +49 221 8809212
