The invention discloses an Internet of Things code distributed analysis method and system and a storage medium. The analysis method comprises Internet of Things code release and Internet of Things code analysis which are performed in sequence. The Internet of Things code publishing comprises the following steps: when an Internet of Things device end changes, publishing an Internet of Things code of the Internet of Things device end and corresponding analysis data to a distributed hash table network (DHT); and when the client needs to parse the Internet of Things code, executing an Internet of Things code parsing process. According to the method, a Kademlia routing algorithm of the DHT is utilized, a'provider mechanism 'is creatively adopted, only a lightweight'data provider index' is stored and distributed in the DHT, and when an Internet of Things code is queried, the DHT quickly returns a list of nodes holding code information. And the query party directly obtains the latest equipment information from the provider. The method is an extremely light-weight operation, almost takes effect in real time, and solves the problem of cache delay of a traditional DNS (Domain Name Server).
