Isn't this a bit overkill? Why not just use an array of "struct in_addr"
rather than an array of "struct in_addr*"? I mean, even if we'd ignore
the overhead of malloc() here, the code is a lot more complex, and on
64bit you use double the memory for storing the pointer to the address
than for the actual address stored... ;-)
