Formodentligt fordi indscanningen af ip-adr sker v.hj.a. sscanf (og
lign.):

	sscanf(inputbuffer, "%i.%i.%i.%i", ...)

Fra 'man sscanf':

      i      Matches an  optionally  signed  integer;  the  next
             pointer  must  be a pointer to int.  The integer is
             read in base 16 if it begins with `0x' or `0X',  in
             base 8 if it begins with `0', and in base 10 other­
             wise.  Only characters that correspond to the  base
             are used.
