I would never discourage anyone from having (harmless) fun.On the other hand, unless your codes postaux are spherical (or a circular projection), your LOC will be at best an approximation of a point in the postal zone. Perhaps the post office, or the geographic center, or a public building, or a monument, or the best restaurant, or...? LOC can't represent the boundaries of most (any?) postal zones, as they tend to be polygons (or with curves, simply a closed path). So the most fun may be guessing the meaning of the result :-)
Still, overall DNS seems to generate more problems than fun, so if LOC provides amusement, it's a good thing.
Malheureusement, LOC's practical application remains unclear. Timothe Litt ACM Distinguished Engineer -------------------------- This communication may not represent the ACM or my employer's views, if any, on the matters discussed.
