what are the ones in bold for? i know that the first 2 are for connecting to the world from both my 10.0.0.7 and 10.0.0.15 interfaces , via gateways 10.0.0.2 and 10.0.0.3 respectively, and 3 and 4 are the interfaces acting as gateways to my local lan, the next two are about broadcasting because of the 10.255.255.255 address... and the next one is the special loopback or something because its 127.0.0.x , but what are the ones with the strange (240) netmasks about?

Those are multicast addresses

Hello carmatic,
224.0.0.0 to 239.255.255.255 are class D Ip address which are used for multicasteing i.e sending multiple copies of same Information to multiple recievers.

Your Frd,
Balli
