I thought my IP has been changing a few times because of blackouts in my area, but AIM and whatismyip.com shows different IPs. My AIM one hasn't changed, but my whatismyip has changed a few times. I've contacted support for some of my sites about my IP changing rapidly, but I don't know which one they are seeing. Can someone tell me which IP freebie sites see, so I know if I should contact support?

You sure AIM isn't picking up your local LAN address? Go to whatismyip.[b175624677c]org[/b175624677c] and it should show your local, private address (at least it does for me). whatismyip.[b175624677c]com[/b175624677c] will show your public internet address, which is what freebie sites should be seeing.

The IP you posted this message from starts with 70.40.xxx.xxx, is that specific enough for you to distinguish between the two you're seeing?

Hm... Whatismyip.org shows the same thing as whatismyip.com.

So the freebie sites should see 70.40.xxx.xxx also?

Interesting, whatismyip.org shows my 192.168.xxx.xxx internal address, so my HTTP headers are probably not being rewritten by my firewall/gateway and it's grabbing the address from there instead of the TCP packet.

Anyway, I don't use AIM so I don't know if it goes through AOL servers or not. AOL is known to do some wonky IP switching on the fly, maybe you're seeing that. Trust what you get from whatismyip.com before AIM, as that should be your true IP as assigned by your ISP (unless AOL is your ISP). I'm pretty sure any freebie site with a reliable script will determine your address correctly.

There was a time with both AIM and Whatismyip.com showed the same thing, but the whatismyip.com has been changing while the AIM IP is staying the same.

Thanks for the help dmorris68

You're NOT on AOL are you? That sounds like something they'd do. I've just recently learned that coming through AOL, IP's can change several times [ie17f647f83]per minute[/ie17f647f83], with each browser hit changing IP's. It's rediculous. No wonder some freebie sites forbid access through AOL.

With the power outages you mention, their routers could be cycling and issuing new IP's when they come up.

I can't think of another explanation outside of those two...

ChaSongjo

No, my ISP is not AOL.

I think it is because of the router, but the freebie sites should be seeing the one that's changing and not AIM's right?

I've only been on giftcards lately.

106 on giftcards, thanks!

You signed up with 70.36.XXX.XXX and only logged in with that one once.

You have another IP that you used to login ALL the other times.

is it 192.1xx.x.xxx?

For some reason its not showing up in the Database. I have to fix a bug.

You're not referring to 192.168.xxx.xxx, are you? If so, [bc7b8962266]that[/bc7b8962266] is your local LAN IP address. It's not a publicly routable IP subnet, and nobody can get to that address from the internet. It only "exists" within the confines of your home network. If AIM is showing you that, it's doing something similar to what whatismyip.org is doing with me -- reading the local IP buried in the application protocol rather than from the TCP/IP packets.

Hm... I must've looked pretty foolish when I contacted support on various sites about this. cry

whatismyip.com is the site that tells the IP address of what we see on a freebie site.

ChaSongjo

30-07-2006 17:23:10

But there are times(actually only twice) when Whatismyip.com shows the same thing as what AIM shows me, does that affect what the freebie sites see? I'm worried about it because if it is changing between the normal whatismyip(123) and the AIM one(abc)...

Then it's actually 5 IP changes, even though it should only have changed once.

1 -> a- > 1 -> 2 -> b ->2

You shouldnt be affected on yoursites by this also.

ChaSongjo

30-07-2006 17:34:50

Does that mean when whatismyip.com and AIM show the same thing, it actually hasn't affected my IP?

I kind of understand now... Thanks YourGiftsFree and dmorris68

That's exactly what AIM does. It shows your local LAN Address. )

Your IP is going to change often unless you have a static ip from your ISP.

Not true at all. My IP has changed maybe once or twice in the past 3 years on my cable connection. Those changes have only occured b/c my modem has died a couple times, and the new modem gets reassigned a new IP.

I'd think you're in the minority though. In my experience most ISP's, cable and DSL included, issue much shorter term leases on their dynamic IP's. The longest I've heard around here in my area is 1-2 months from the cable ISP. My DSL IP has a 2 or 3 week lease time, and I rarely get the same IP after lease renewal.

Whats with all the concern about IP addresses? Lots of people still have dial-up, don't they? And with that they get a new IP address every time they log-on. I don't think having DIFFERENT (multiple) IP addresses is such a big concern. The problem is having the SAME one as somebody else.

[quote956958df62="tuxmaskone"]The problem is having the SAME one as somebody else.[/quote956958df62]
And that's exactly the (potential) problem right there with dynamic IP's. )

Here's an illustration let's say you and I live in the same area, and are serviced by the same ISP. That means we share the same block of IP's. I have IP 1.2.3.4 today when I join a freebie site. Tomorrow I get a new IP, 2.4.6.8, but you happen to get 1.2.3.4 after I've given it up, then just by coincidence you signup for the same site I did. To the site owner it could appear to be the same computer doing the signup.

It's a situation with fairly low odds of happening, but it can technically happen (and I'm sure it has at some point). That's one of the reason that IP alone isn't a reliable indicator of fraud, but when taken in context with other information, can be a deciding factor.
