You could use the tcllib dns package to do async dns lookups. If your
setup is sane and you have a caching dns server, you could do the following:
1. use tcllib dns client to seed the upstream dns cache, if it fails the
query will probably fail too
2. use the usual http call and get the cached name from your dns server
An other approach might be to use the async dns lookup and than use
numerical ips in your query.
