An IP management method, a client and a server. The method comprises: searching, by a client, a first correlation table, and determining an IP address of a server corresponding to the type of a service to which the client needs access, the first correlation table being a table of the correlation between the IP address of the server in a service cluster saved by the client and the type of the service; sending, by the client, an access request to a server corresponding to the determined IP address of the server, the access request containing the type of the service to which the client needs access; and receiving, by the client, access data which is fed back by the server and corresponds to the type of the service to which the client needs access.
