The present invention relates to an apparatus and method of looking up an IP address using a Bloom filter and a multi-hashing architecture. The present invention generates a plurality of hashing indexes by hashing inputted prefixes, determines whether a bit vector corresponding to the plurality of hashing indexes is positive or negative by using the Bloom filter, and outputs a prefix matching the inputted prefix by searching entries of locations indicated by the plurality of hashing indexes in the hash table when the bit vector is determined to be positive. The present invention further outputs the prefix that matches the inputted prefix by searching entries stored in the overflow table. |
