Don,
Those problems were resolved yesterday. Rip44d has been updated to version 1.3, it now correctly adds routes to the kernel routing table (which are referenced by their network address and CIDR prefix).
The 0's refer to the routing tables and CIDR type routing, which for a /24 (or 256 IP host network), the network [address] begins at 0, the first usable address is 1, and the broadcast is 255.
Prior to the rip44d fix, the problem was rip44d-based routers would only have 44.182.21.0 (a single IP address, /32) in their table, instead of 44.182.21.0/24 (which references 44.182.21.1-44.182.21.254). Therefore, Marius and I couldn't ping each other because I did not have a route for the IPs 44.182.21.1-254.
