Looking at my login history (at https://openid.stackexchange.com/user) I see I've logged in several times from the IP address "" but according to a quick whois search, that IP belongs to "Stack Exchange, Inc." I'm imagining it's probably a bug in SE's logging but wondering if it could be a loopback / IP spoofing attack by some bot or...?

Irrelevant info to pre-empt off topic questions:

  • Because I found my email (again) on https://haveibeenpwned.com/
  • Yes, I had a weak password on here (relatively speaking; it was under 15 chars and used my old pre-salting technique)
  • No, I do not see any unusual activity on my SE account
  • Yes, I changed the password
  • Does anyone else see similar activity or is it just me?

    I think its a semi known bug. I've seen it a few times as a mod. Jan 18, 2019 at 14:35

This is likely the remnants of an internal API call on our end, which we will be deprecating soon, OR possibly you have found your home is a wormhole in which you exist both there and our NYC office at the same time!

This post on meta has more info about the sunsetting of OpenID which will likely make the SO IP stop popping up for you like that.

Either way, I wouldn't worry about it. Best case scenario you can pop in for a NYC slice and be home in time for dinner.

    Is that NYC slice for cheesecake or pizza? In either case, now I want to partake in this bug; and I won't have to be home in time for dinner. Jan 18, 2019 at 16:50

    Great question, I meant pizza but the cheesecake is also delicious. Basically YMMV. Jan 18, 2019 at 16:55
