I have encountered a bug while using mIRC v7.72 with the InspIRCd v4. The issue is related to the display of IP addresses on /whois response of the user. Currently, the IP address format appears as "IP is connecting from," Like: [09:43] 94.***.**.** is connecting from while it should display as "is connecting from ident@hostname ip address."
