Provided are a method and apparatus for scanning of a station in a wireless local area network. The method includes: receiving a probe request frame including probe request relaying information from a probe requesting station (PRSTA) initiating the active scanning, determining whether to discard the probe request frame (PRF) when a frame related to relaying of the PRF is received, determining whether to relay the PRF, and relaying the PRF to an access point if it is determined to relay the PRF, the probe request relaying information including: a transmitter address field indicating an address of a station (STA) transmitting the PRF, and a PRSTA address field indicating an address of the PRSTA, wherein discarding of the PRF is determined by comparing one of the transmitter address field or the PRSTA address field with information included in the frame related to the PRF.
