I have yet to see an ISP who offers dynamic reverse DNS for their IP blocks. For that matter I have yet to see an ISP offer DDNS at all. The ISP will own the reverse domain and will map your IP to something like Obviously, only your ISP can practically do reverse DDNS. The fact that I can post and my forward and reverse names are different seems to imply that maybe just having a reverse entry suffices. I trust that the data shows that this restriction has sufficient benefit to justify excluding users who through no fault of their own don't have a PTR. -Andrew- -- ______________________________________________________________________ | -Andrew J.
