Thanks Deepak, Ryu, and Dan, for your timely responses. As Deepak pointed out, there was a non-NULL value in the cidr_v6 column which was creating this issue. Since the default behavior is to not process ipv6, I did not think that the implementation would be looking at this value. However, it seems like even in that case, the system does look at this. Setting it to NULL helped get past this.
Thanks, ~Sumit.

Usually see this exception in netaddr when cidr is invalid. Just check if cidr_v6 of the network is not empty or in invalid format. if you're not using v6 addresses you may need to disable ipv6 in your setup.
