MD5 isn't a consistent hashing algorithm. Consistent hashing is a scheme that provides a hash table functionality in a way that the adding or removing of one slot does not significantly change the mapping of keys to slots. With that said, a lot of consistent hashing algorithms USE md5...but it alone won't get you all the way there.
