The Dynamic Host Configuration Protocol (DHCP) request of a user device is received, and the request carries the option which is used to indicate returning the domain name of the local domain in which the user device is located (S200); on the basis of the DHCP request, the domain name of the local domain in which the user device is located is obtained, and the domain name of the local domain in which the user device is located is carried in the DHCP response message and is returned to the user device (S202). Also provided in the present invention are an apparatus and system for obtaining a local domain name, solving the problem of users being unable to obtain a local domain name after full authentication. This enables the user device to perform fast re-authentication during a handoff, reducing handoff time delay and improving the user experience.
