[CLUE-Tech] reverse DNS

[William]

Simply put, it serves something like an ID card for your host.  Additionally, thanks to the
delegated nature of DNS and who controls the DNS servers, it is much more difficult to spoof than,
say, an SMTP HELO response.  I can't say how many thousands of hits I get against my servers ever
day that 'claim' to be one host, when their RDNS lookup indicates who they truly are -- usually
dial-up, cable, and DSL users, all from dynamic IP beds.  Spoofing is rampant, and RDNS help to
keep it in check.
