Dynamic DNS registration method, domain name solution method, DNS proxy server, and address translation device

摘要

The present invention relates to a domain name solution method in dynamic DNS and a device for domain name solution. A dynamic DNS server includes an address translation means which assigns a host a virtual address corresponding to an actual address of the host. The dynamic DNS registration method comprises a step in which the address translation means assigns a virtual address to the host upon a registration request issued from the host and a step of storing a tuple of the actual address, virtual address, and domain name of the host, which are associated with each other.
