Najskor je niekde slucka v routovani. Aby v takom pripade
nebludili po sieti pakety do skonania sveta, ma paket
nastavene, kolkymi uzlami moze prejst. Ked ten counter
spadne na nulu, uvidite vyssie uvedene.

Skuste traceroute, ten prave tuto vlastnost vyuziva
na zistenie trasy (postupne zvysuje time to live
a pozera, odkial mu pride vyssie uvedena hlaska).

Zdravi
