does any one know of a free reverse dns server that's good? the dns servers my isp provides frequently fail to identify the owners

to identify all those ip#, many of which are incursion attempts by dsl or dialup or cable modem users on other isp's, and many
of which are advertising or tracking sites (which i aggressively block for privacy and because the ad servers tend to be overloaded
and greatly slow down surfing, especially since i'm limited to dialup at present).
Chances are that if your ISP's dns is not giving you a reverse for IP's, there isn't one, or your ISP's DNS is severely borked.
along the same lines, i'm considering getting a cable modem in the future, but of course there are security issues, are there services set up such that i could have ssl or vpn contact to a remote machine and they would reroute it to the actual destination so that my communications would be secure on the cable line (i.e. encrypted) and then routed on the backbone unencrypted to sites that don't use encryption or parts of sites that don't?
Why? Are you suggesting that your local cable network is more insecure than the Internet at large? You have to remember that once packets leave your ISP's gateway, they may travel through many untrusted networks before reaching final destination. Encryption to your cable providers gateway would gain you nothing. A more sane approach would be to use Freeswan's "Opportunistic Encryption" which creates an IPSEC tunnel to other public machines that support OE. This would give you encryption to a small sub-section of the Internet. -- -------------------------- M.
