Title: DOMAIN NAME ACCESS METHOD AND DEVICE
Abstract:
The present application relates to the field of Internet communications, and provides a domain name access method and device. The method comprises: a user equipment determines that the user equipment moves from a first location area to a second location area; the user equipment sets a first Internet Protocol (IP) address in a domain name cache to be invalid and sends a first domain name resolution request message to a domain name system (DNS) server; the user equipment receives a first domain name resolution response message, the first domain name resolution response message carrying a second IP address corresponding to a domain name; the user equipment adds the second IP address to the domain name cache; the user equipment accesses the domain name by means of the second IP address. By triggering the update of a domain name cache when it is determined that a user equipment moves between location areas and accessing a domain name by means of an updated IP address, the present application can implement the access to an optimal server corresponding to a domain name by the user equipment, and features a short delay and high communication efficiency.
