Re: I'm confused

I think you missed three things:

1) IP address to name reverse lookups are not unique. I can look up many different names to get the same IP address. This is particularly relevant when reading blogs (thousands may be hosted on a single server, including many bland ones and some radical ones) and can also be relevant for CDNs.

2) You may be using a VPN, a proxy server or even Tor to protect your network connection but many browsers still look up the name first (for example, that is the default configuration in the version of Firefox I use).

3) A matter of principle: name lookup and network connection are separate issues and both need to be protected (otherwise your question could just be raised the other way around).
