Fix invalid reads/writes due to incorrect sizeof().

Browse Source 
These few places in the code used sizeof() on h_addr in struct hostent.
This is sizeof(char *).  The correct way to get the size of this address is to
use h_length.  This error would result in reads/writes of 8 bytes instead of 4
on 64-bit machines.
