Since you can't change the code, it's almost certainly the best
solution available to you. It's more-or-less equivalent to speeding up
your DNS lookups massively. The main downside is that if something
changes, you need to change it in DNS and in your hosts file; as Roy
says, it's a pragmatic solution rather than a perfect one.
