I'm trying to debug a networkmanager problem. I've found this xml file:

"routes" mtime="1236774478" type="list" ltype="int">
       </entry>

               <li type="int" value="1814304715">

Well, 1814304715 in binary is 01101100 00100100 00010111 11001011 which when you convert the grouping of four into a dotted series of octets you end up with 108.36.23.203 - which may or may not be relevant to your network, I'm just guessing that the integer addresses are the integer representation of the binary for the IP addresses ;)

               <li type="int" value="24">
               </li>

My guess is this is the number of bits assigned to the network - in other words, the netmask is 255.255.255.0 (or /24 in CIDR notation)

               <li type="int" value="-31189045">
               </li>

Cheers,

Again, assuming this is an integer representation of the binary (and assuming 2's compliment) we end up with 254.36.23.203 (after ignoring the highest 32 bits which are all ones) - which looks like a multicast address. I have no idea if this is how things work in Gnome world, but it was fun to blow the cobwebs off my binary arithmetic on a long weekend!
