    link from 1.2.3.4 to 1.2.3.5 added
    duplication of 1.2.3.5 to 1.2.3.4

    ...
    the nodes are: 1.2.3.4, 1.2.3.5, 1.2.3.6, 1.2.3.7
    the links are: 1.2.3.4=1.2.3.5,1.2.3.4=1.2.3.7,1.2.3.5=1.2.3.6,1.2.3.5
    +=1.2.3.7,1.2.3.6=1.2.3.7
    a shortest path from 1.2.3.4 to 1.2.3.6 is: 1.2.3.4 => 1.2.3.7 => 1.2.
