ABSTRACT = {Nowadays, more and more smartphones communicate to each other’s by using 
some popular Next Generation Instant Messaging (NGIM) applications (Apps) 
which are based on the blockchain (BC) technologies, such as XChat, via 
IPv4/IPv6 dual stack network environments. Owing to XChat addresses are 
soon to be implemented as stealth addresses, any DoS attack activated form 
malicious XChat node will be treated as a kind of DDoS attack. Therefore, the 
huge NGIM usages with stealth addresses in IPv4/IPv6 dual stack mobile 
networks, mobile devices will suffer the Distributed Denial of Service (DDoS) 
attack from Internet. The probing method is deployed in this paper by using the 
active ICMP (Internet Control Message Protocol) protocol. Thus, the aim of this 
paper is to provide the active approach based on the integrated entropy 
calculations for the NGIM traffics, the numbers of IPv4 and IPv6 addresses of 
the abnormal events found and counted after active inquiring ICMP procedure. 
However, many DDoS attacks in Internet were found to paralyze NGIM Apps on 
smartphones. It is a lightweight approach could be applied in mobile device.},
