The embodiment of the invention discloses a domain name system DNS processing method and apparatus. The method comprises the following steps: if the handover of an access network of a terminal device is detected, initiating a DNS query request of a target domain name; receiving a DNS analysis result corresponding to the DNS query request, wherein the DNS analysis result comprises at least one first IP address corresponding to the target domain name; and storing the first IP address in the terminal device. By adoption of the domain name system DNS processing method and apparatus disclosed by the invention, the problem that a target network position cannot be accessed quickly after the handover of the access network of the terminal device in the prior art can be solved, and the user experience is improved.
