A dynamic network feature processing device includes a storage medium and a processor. The storage medium is configured to store a plurality of malicious feature groups, and each malicious feature group corresponds to a malicious feature. The malicious feature group includes a plurality of malicious network addresses. The processor is coupled to the storage medium. The processor is configured to acquire an unknown network address of an unknown packet; compare the unknown network address with the malicious feature of each malicious feature group; and filter the address with the malicious feature of each malicious feature group; and filter the unknown packet when determine that the unknown network address satisfies the malicious feature of at least one of the malicious feature group.
