Abstract: Disclosed in embodiments of the present invention are a method and an apparatus for assigning an IP address, so as to simplify the process in which a GGSN assigns an IP address, and improve performance of the GGSN. The method in the embodiment of the present invention includes: receiving a request message initiated by the GGSN for creating a service PDP context for a user; obtaining a service list of the user; selecting a service with a different APN out of services recorded in the service; determining whether a same VPN exists in VPNs corresponding to the services with the different APN, and if not, sending a response message of creating a service PDP context for a user to the SGSN, and activating a service PDP context by using an IP address of a default PDP context as an IP address of the service PDP context.
