The whole point of using wildcard DNS in my regard is if you got a production website, you would point *.yourdomain.com to the IP address to redirect impotent users to your homepage, then you can rewrite the HTTP_HOST header with mod _rewrite making it seem like they didn't mistype it which is actually good, but either then that I wouldnt see the use. ----- Original Message ----- From: "Tony Landells" <ahl@austclear.com.au> To: "Christopher Leigh" <clcont@gmx.net> Cc: <freebsd-questions@FreeBSD.ORG> Sent: Thursday, April 26, 2001 11:26 PM Subject: Re: *.example.net > I've never heard of anyone doing wildcard A records... > > Back in the days when people weren't very good at hiding hostnames > in email they used to use wildcard MX records.
