Summary:Nowadays 21 centuries are the information ages that a networks are cores， under the condition that condition allow next， more profession， personal start set foot in the network The network technique also changes with each passing day in this kind of trend of But， also exactly this kind of unprecedented prosperity， but bring， the network resources burden becomes to gather the product to To know， the network resources is limited， but the need is Also exactly and thus， the network resources acceleration consume， starting the condition of appear the supply falls short of But， the need of information world to the network resources that fly to develop soon but only ability is there is 増 did not Hence， the technical personnel hopes and can find out a kind of new technique method， solve the influence of the increasingly dried up network resources upon the information world and thus satisfy the mankind's increasingly multifarious network So the son net divides the line the technique is very important， it alleviated the depletion of the network resources effectively， making the network resources get the reasonable A little bit say in brief:While diding not divide the line the son net technique， the Internet traditional resources allotment way is compare an IP address is divided into the network number( net- id) and the host number( host- id)， and join 5 categories of 1~ in the part network especially， compare through a category especially is divided into address of IP A， B， C， D， the E five， but these biggest differentiations are again in the by volume dissimilarity， and the host dissimilarity But this kind of traditional allotment method， have a lot of Among them included the above-mentioned network resources to consume to quickly wait the very tough In this kind of case， pass to divide the line the son net technique and can resolve the above-mentioned Its thought is:Is in the whole piece of space of IP that you get， pass the son net 掩 code to divide the line a son net again， thus， the same can satisfy the correspondence need of each At the same time， the son net and the network addresses combine together， not only can combine the host that locates the different physics position together， also can pass to separate the key equipments or excellent turn the safe function of the measure exaltation network of of the data transmission， lower the network Thus， can with reasonable and use of economy network Can say， divide the line the son net technique is mankind in the information technique， the heroic act of the milestone The network technique develops till today， the plait address method of the address of IP has already experienced three important history These three stages is: (1) Classified address of IPThis is the most basic plait address method， passing the homologous standard in This is also the most traditional IP plait address (2) The demarcation of the son This is the improvement to the most basic plait address method， its standard[950] of RFC passes in (3) Constitute the super This is newer without the type classification plait address After put forward in 1993 very quickly have to arrive the expansion In this text， we will pass the detailed introduction of this main line， dividing the line the son net technique to the function that network produce， and divide the line the technical and concrete contents of the son
