There is a pre-existing alternative provider, dnsjava:
dns(only)-based providers are not the best option for general purpose resolving because (besides the fact that they will not use alternative naming methods which are typically used (mDNS, WINS, Hostsfile)) they also cannot use the more advanced functions of the system library (together with the kernel) for address selection.
Let me quote a section of my presentation* :=) , the links contains some background on the address selection
“A lot of the information used by the sorting algorithm is not easy to come by. It is therefore highly recommended that no program uses home-grown implementations of getaddrinfo(). Just use the system implementation.” (Ulrich Drepper, 2007, http://www.akkadia.org/drepper/linux-rfc3484.html)
Having said that, DNS-only based implementations do have their use. dns,sun and dnsjava are on my list to check out :)
