For the IP, some internet providers using an IP Static from their service.
Sometimes your IP will be changed every 1 hour, a couple of times or went you on a different area. All my provider internet in my country most of them using IP Static, so probably i can't really get the same IP with yesterday except for WIFI. But its kinda weird went the "holding fund" trigger on the different address too, if they triger with the IP could be normal.

It doesn't really matter all that much if your ISP changes your IP because in short you are still shown at the same place with your IP
My IP address changes in every hour, because it is not a static broadband provider, I use a shared server so there is no fixed IP. Yep, if IP changes it is not a problem, it always shows the same location. the main problem is, when your IP changes, sometimes a confirmation message often appears on mailbox, it is rally annoying. On all website do not send confirmation messages, but some websites do. I've played on FJ with TOR browser, there is no problem at all.
