Can a dynamic IP set itself to an IP someone else once used?

I have a dynamic IP which changes itself every so often.

I just tried to go to 4chan and I got the message I had been permanently banned for started a 'jailbait thread' on 14th January 2010. Now, I did no such thing because

a] I've never started a thread like that
b] I wasn't even living here in January 2010

The 'appeal' box had the gmail address and appeal plea of the person who had been banned still written in it. Weird.

Anyway, I just reset my router and I can access the site and my IP has changed.

So clearly your IP can set itself to someone else's old IP - and you can get in trouble for anything associated with that IP. That's a bit off, isn't it? Or does the IP cycle with various combinations which are always related to to the same property?
 
Yes, its a dynamic IP, there is a finite pool of IP's for each ISP and each area, so its entirely possible to get an old IP, in fact I would say every IP has been used before. Probably multiple times. Same as phone numbers.
 
What often happens is something like ISPs use caching proxies, etc. especially for sites that get a lot of traffic and the site actually sees the same IP or a limited range of IPs for a huge range of customers - one person misbehaving can get the gateway IP from your ISP banned cutting off a lot of customers.

Theres also entire sites I can't visit without using a proxy because the stupid web site owner has banned the entire IP range for my ISP due to a small number of people misbehaving - cutting off a lot of people who have a good reason to visit the site while doing nothing to stop anyone out to cause trouble as most of them are switched on enough to use proxies.


Gotta love the retarded ways some people manage their web servers.

That explains it, how annoying. So it's not confined just to one property? Anyone could get that IP from that ISP?
