Within this paper, we advise a minimal-overhead identity based distributed dynamic address configuration plan for secure allocation of IP addresses to approved nodes of the managed mobile random network. A brand new node will get an Ip from a current neighbor node. Within this paper, we advise a safe and secure distributed dynamic IP configuration (IPv6) protocol termed Secure and Distributed Robust Address Configuration (SDRAC) protocol for address allocation inside a managed MANET employed for mission critical applications where authentication of nodes is essential. After that, each node inside a network has the capacity to generate some unique IP addresses from the own Ip, so it can further assign to more new nodes. Our suggested protocol takes proper care of these problems incurring less overhead as it doesn't require any message flooding mechanism within the entire MANET. Because of insufficient infrastructure, aside from security issues, this particular systems poses several design challenges for example high packet error rate, network partitioning, and network merging. Performance analysis and simulation results reveal that despite added security mechanisms, our suggested protocol outperforms similar existing protocols.
