We’re having a bit of a problem on https://community.infinite-flight.com
Seems like the IP address lookup is partially failing.
As far as i can tell, it only fails to retrieve the location & ISP data of the IP address in question and duplicate accounts are displayed properly. I’m not 100% sure of the duplicate detection though, as i haven’t seen any recent lookup of new members displaying duplicate accounts and we usually have a few each day.
Seems to be the same regardless of IPv4 - IPv6.
