With the development of cloud computing, Internet of things, LTE and other emerging business and technology, the IPv4 address shortage problem is becoming increasingly prominent. This paper is based on the demand of address in the process of mobile packet domain to IPv6, and a construction scheme to solve the problem of address shortage is proposed. Coupled with the surrounding network situations, the demand of rebuilding some neighboring network elements is put forward accordingly. Before the widespread usage of IPv6, this paper provides an effective way to solve the conflict problem between the rapid development of telecom service and the lack of IPv4 addresses.
