Abstract: Disclosed in the present application are a domain name access method and device, used for increasing the communication efficiency of a terminal device. In the present solution, after implementing resolution of a domain name requested by a terminal device, a DNS server sends the resolved application server IP address and usage condition information to the terminal device. Thus, when the terminal device moves and the information thereof changes, and the terminal device does not meet the conditions indicated by the usage condition information, the terminal device can re-implement DNS resolution of the domain name. When the terminal device does not meet the conditions indicated by the usage condition information, the previously resolved application server may no longer be the most suitable application server for the terminal device; by means of the present solution, the terminal device can re-implement DNS resolution of the domain name and thereby acquire the most suitable application server; thus, the present solution improves the communication efficiency of the terminal device, and avoids the wastage of transmission resources in the communication system.
