Your customers may think that the server is slow, but actually it is just waiting for the DNS resolution response. You can use it, but if you want performance, you should avoid it, or schedule it to some CRON script I have written two functions to implement this.
I don't believe this issue has been addressed yet. I'm getting. Note that if you pass an IP address to gethostbyname it will return that IP address. I had difficulty getting gethostbyname to work under OpenBSD 3.

To get PHP's gethostbyname to work, you need resolv. On a side-note, PHP 5. In short, once PHP looks up an address, it may not actually perform another lookup as you may expect.
