Hmm... perhaps, yeah, but as long as I can get the Reverse DNS/IP address
found, I can work on planning a banner that 'estimates' certain values.
I see what you mean though, but it would still be handy to find out how to
find the Reverse IP/DNS anyway.
Does anyone know?
Maribeth, thanks for your suggestion, but I need to know the PHP code in
which I can do that myself, as I need it desparately to improve a user ban
system.
Thanks for your help guys!
Regards,
Dan

Subject: Re: Reverse DNS/IP
Daniel,
I don't think this is going to help you much. Most ISPs assign unique DNS
names to each IP address, so you'd end up with something like:
92-18-36-1.wsip.mysip.com
the first time they come in, and
92-18-36-2.wsip.mysip.com
the next time ... if you ban based on DNS name, you're still hosed since
they correlate exactly (1:1) to the respective IP addresses.

Hi guys,
Question:
I was wondering if anyone knows if it is possible to find the reverse
IP/DNS address of a computer please?
Reason:
I ask this because I wish to produce a 'ban' list of users on a forum who
persistantly cause problems, banning specific IPs is an option, but at
the moment is not effective because the IP address of one specific user
changes, they have a dynamic IP which means they are either using
Dial-Up, or specifically paying with their ISP to have their IP refreshed
every computer log-in (or Internet box reset).
IT's all well and good using $_SERVER["REMOTE_ADDR"]; to help use as a
"ban" function, but if the IP keeps moving all the time, it isn't
working. So we need to result to a Reverse DNS which doesn't change, it
remains the same.
Question:
Is there a way of finding the Reverse DNS address through PHP please?
Thanks for you
