And as I mentioned somewhere earlier,
icmp message based approach assumes try-and-error mechanism at host.
So, the difficulties mentioned here still remain, such as,
- the effect to applications. They may require rewriting.
- caching algorithm complexity.
- possible flooding to the server and the router.
- working address pair is not always desirable.
... and something I'm missing now.
