Agreed, but many ISPs, including some very large ones, don't seem to have the technical ability to point reverse DNS to the domain's name server for a proper reverse lookup. Over the past ten years and five ISPs, only 1.1 have gotten it right. (The .1 is that one of them got it right for a month, then broke it and was never able to fix it. The one that did get it right stopped servicing my area after a year.) Right now, some of mine point to generic ips and some point wrongly. I have spent more than 200 hours with the current ISP trying to get it fixed, but so far no success--and yes, I have always had business accounts with static ip-addresses. If anyone has had success in instructing ISP personnel on how have a reverse address correctly refer to the proper name server I would like to hear the method. (Giving them the page number in the DNS & BIND book doesn't seem to work. Even getting them to understand the request seems as difficult as getting a paper airplane to the moon.)
