Research of DNS Worm in IPv6 Networks

In IPv6 network environment,the scanning strategy of Internet worm was analyzed.A new type of worm,DNSWorm-V6 was built.The worm applies two different layers scanning strategy.It means that the worm applies subnet scanning strategy in local subnet and applies DNS scanning strategy in inter-subnet.Based on the two layers scanning strategy,a Two-Level worm propagation model,TLM was presented.The results of simulation experiment show that DNSWorm-V6 is a worm that can propagate fastly in the large-scale in IPv6 network,at the same time we can predict the threat probably posed by the new worm in IPv6 network.
