In this paper, we proposal an content provider mobility solution of Named Data Networking (NDN) [1]. Here content provider means the host of NDN network which provide content originally. We add a Locator are to the Interest packet [2]. Mapping System also introduced into the network, which maps identifier to locator. The original name is used as identifier. Thus, matching lookup in Content Store (CS) and Pending Interest Table (PIT) employs identifier, while forwarding lookup in Forwarding Information Base (FIB) employs locator. In reality, Mapping System should be a DNS-like distributed system, so the record updating has time latency. It's hard to solve provider mobility when there is no explicit "where" information, that's why locator is imported in NDN, however, "where" still serves as the secondary information of the network.
