Thanks again everyone, I've read through your posts and there's several points that seem to relate to the user i mentioned. We're not sure if they're using a proxy, they've stipulated they only use variable but then again without going in further we can't be sure there.
The forum has less than 30 members, apparently it isn't just two members under question but three which makes the possibilities of there being separate users even less than remote.
I myself last night witnessed a tirade this user set onto the admin, it wasn't pretty and it seems they were out to cause trouble. Amazing how someone can change their way of posting :rolleyes:
If there is any further developments though, I'll let you know, at the moment we're going with the 'lying' theory. You've explained IP addresses to me very well, I knew a lot of it but have been pleasantly surprised to learn even more. It's all taken on board in case it's needed for the future. Cheers
i run a forum with 15000 users. it's best not to ban people permanently, because they just sign up again. you have to ban them for a period short enough to prevent that, but long enough to be a punishment. that having been said you should also try to phrase your warnings as though a temp ban is not a punishment but designed to help prevent them getting themselves into more trouble and to help the smooth running of the forum. emphasise the effort involved in running the forum and how you need to do this in order that you can help get on with your actual job.
the first two lines of our rules are: These rules are intended as a brief guideline any exceptions or amendments are entirely at the discretion of the moderators.
Above all, common sense, respect and courtesy should guide you in deciding if something is within the rules or not, as such we reserve the right to take any actions we deem necessary, up to and including permanent banning, to ensure the smooth running of the forums.
try to come at it from that angle. if you piss people off they can do quite a bit of damage.

Thanks flagpole, it's funny you should say that actually. We have one person out to cause harassment for another member, they've been banned so many times. We find them looking in as a guest and within weeks they're signed up again..it's never ending.
The user we've been concerned about now is the type to cause trouble. Last night they caused the admin on the other forum some grief and caused a huge row because they'd been caught so what you say here makes sense and I shall inform the admin and other mod on our forum about this.
I've used the link you gave me and it's excellent..it gave me instant info we need and we shall use it in future when any problems arise. Your wording here is a good way to get the message across to members..thanks again
i've been doing this for a while. i'll give you the full wording of our rules, minus the ones that are quite specific.

NO way
.If two computers on the same network have the same IP address ... well, the results are unpredictable. It depends on how all the other equipment on the network handles the problem. In general it could be as bad as both machines not being able to communicate at all. More likely only one will not be able to, or perhaps there will simply be intermittent problems on both.

What kind of searches are you doing on DS to find 4-year old threads?
I think mobile operators do reuse IP addresses actually, perhaps using some form of NAT.
A quick Google suggest some form of Carrier Grade NAT (CGNAT).
reusing IPs is different to having the same IP on 2 different devices on different accounts and in different areas.
besides, it breaks the possibility of being able to monitor for security purposes.

The devices will have different addresses on the private network, but will share a public-facing NAT'd address, so if they both visited the same website at the same time they would show the same address to that site.

yeah but then the device would be displaying the private network IP address and not the public facing one - exactly the same as a corporate network behind a proxy.

Not from the website's point of view - it would see both connections as coming from the same IP address. The private address would not be visible and not be rotatable from the website.
Yes, on the private network. However, it wouldn't be something the OP could have used (four years ago!) to differentiate between two connections from the same user, or two distinct users.

yes, and the devices still have a unique IP address.
the person said the 2 devices had the same IP address, they don't.
What you don't know is how the person obtained the 2 IP addresses. In all probability they obtained the global IP address seen by the internet rather than the local IP address used by the mobile provider, in that case it is quite possible for them to be the same.

Perfectly plausible scenario:
Two people buy MiFi devices on the same operator's network.
They fire up their laptops, and connect to the WiFi network provided by their MiFi device.
Both laptops have private IP number 192.168.0.1 (or whatever the first allocation from the default DHCP pool on the MiFi device is).
Both people then visit whatismyip.com (or whatever).
They may well see the same IP number, because mobile operators use CGNAT to hide their entire network behind a very small pool of external addresses.
The same scenario would occur were two people to buy low-end internet connections from BT or Plusnet (I think): their home devices would get addresses from the bottom of the 192.168.0.0/24 pool (or whatever), and whatismyip.com would show the external address the customers are NAT'd into.
In both cases, the distinguishing IP number would the outward facing interface of of the MiFi device or home router, which may or may not be easy to get hold of.
Roll on IPv6. I've at last got native IPv6 both at home and in each of the data centres I have equipment, which makes life much easier.

but if you could post the details that come up when you post it into here:

that would be useful.

That's great..I'll go and sort that now..cheers Flagpole.

Welcome, by the way. ;-)
not possible.
2 people can't have the same IP address at the same time and the connection to still work.
