 Hi,
 
 This bug can't be fixed very easily.  The problem is that element
 ut_host of struct utmp in include/utmp.h is fixed in size at 16
 bytes.  Although I'm sure there is probably a way to obtain the
 raw addresses and print them out in who(1)/w(1), it is probably
 not worth it.  The easier solution would be to expand UT_HOSTSIZE
 from 16 to 40 (8 * 4 + 7 + 1 for NUL).  However, that would break
 the ABI and can only be done on -current at the right time.
