Ray,

   This works if you do not have weird NLS settings :

  1  select address from ip
  2  order by to_number(substr(address, 1, instr(address, '.', 1, 2) -
1)),
  3*          to_number(substr(address, instr(address, '.', 1, 2) + 1))
SQL> /

ADDRESS
--------------------
10.0.12.1
10.0.78.1
10.0.112.1
10.0.113.1
10.0.113.2
