A method is proposed to compute the continuum of paths, from shortest paths to all random paths between all pairs of nodes at once in a unified way. The analysis is based on treating the network as a random walk with an additional absorbing state named evaporating state reachable with nonzero probability from any state (so called "evaporating random walk"). The probability of avoiding absorption is tuned by a single parameter varying between 0 and 1, with lower values favoring shorter paths. A computational example is used to illustrate the method.
