You need to start with getaddrinfo as a starting point. Yes, you can get
to the raw data if you want to but now you are crafting custom solutions
that only work for DNS calls. The O/S implementations of getaddrinfo()
encompass more than just DNS. Look at Solaris for example. I don't
believe that the TTL is the best solution to this problem, BTW.
