Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 158 Stack Exchange communities.

What is meta?
Here's how it works:
  1. Any Stack Exchange user can ask a question
  2. The community provides support, votes on ideas, and reports bugs
  3. Your voice helps shape the way Stack Exchange operates

I've just checked my IP addresses on Web Apps (Link for Web Apps mods and developers):

and a couple show up as being used once but the weird thing is they resolve to South Africa - somewhere I've never been.

Is this someone trying to hack my account or just an artefact of the way the internet routes data. There's no data information on when these IPs were first and/or last used so I don't know whether this is a recent thing or not.

The dns lookups resolve to Durban and Johannesburg and the names end in "" implying (I think) that they are end user addresses.

The IP cross reference table shows some interesting things also:

Other users, who live in completely different continents appear to share the same IP addresses as me when I know that I have a static IP at home and I assume the company where I work does too.

Be honest; what'd you do to Diago? – Pops May 6 '11 at 16:39
Does the IP cross-reference show anything? (A tool I admittedly normally ignore for mods, since in my case it shows that I have 7 sockpuppets, including Community and another mod) – Michael Mrozek May 6 '11 at 16:41
@Michael - the cross reference - shows that some users are using MY ip address (which I find harder to believe). – ChrisF May 6 '11 at 16:44
Huh, thought I'd check my own on SU, should I worry that I've apparently used over 500 times...? – DMA57361 May 6 '11 at 16:50
@DMA It says that for everyone. I've never heard of it picking some random address in South Africa though (although it's probably the same kind of thing; I doubt very much it's actually somebody logging into the account from that address) – Michael Mrozek May 6 '11 at 17:01
@Michael that's OK then, I'd assumed that was probably the case as I've seen it on other people's lists as well, so I'd not bothered to raised it before. This just seemed like a good opportunity to do so. – DMA57361 May 6 '11 at 17:03
I checked on Drupal Answers, and the cross-referenced IP addresses table says I shared my IP address with @Jeff Atwood. The problem is that I have connected to Drupal Answer from my house in Italy, while Jeff Atwood is in California. How can it be possibly true? – kiamlaluno May 24 '11 at 11:42
Didn't you get the answer to this the other day? – Grace Note Jun 6 '11 at 13:53
@Grace - yes, but only in chat. Someone needs to post an answer so I can accept it. – ChrisF Jun 6 '11 at 14:13
@PopularDemand - I've forgotten what the answer was now :) I do remember that the last comment was to prompt Grace to answer. – ChrisF Nov 3 '11 at 20:26

The answer is that when a post is migrated by a moderator the post history on the destination site stores the user id of the post owner but the IP address of the moderator doing the migration (don't ask me why - ask the team).

This means that stuff migrated to Web Apps will have the IP address of the SU (say) moderator and that's why Diago's IP address appears in the list and my IP address appears against other users.

This was fixed a while ago, so it shouldn't happen on migrations today anymore (unless you have a recent example?) – balpha Nov 3 '11 at 21:14
@balpha - no. Just that Popular Demand prompted me to answer given that no one from the team did.... – ChrisF Nov 3 '11 at 21:23
That's fine, just making sure. – balpha Nov 3 '11 at 21:25
Whoops, I totally forgot to follow up here when we looked at it / fixed it. Sorry Chris! – Rebecca Chernoff Nov 3 '11 at 22:52

Any chance your OpenID provider is hosting in South Africa, and IP addresses used during log in are also recorded?

(For any moderator who can see my IP addresses: x.x.99.180 is me; x.x.169.19 is used for my OpenID.)

I don't think so - it looks like each IP address only has been "used" once. Most visits are from my home IP and what I assume is my work IP. – ChrisF May 7 '11 at 19:36
