The article feedback extension stores IP addresses of anonymous users in a 32-character field (af_user_ip varchar(32) NULL), possibly assuming the IP address is normalized to a colon-less form. Which is not the case, and a 40-character field is needed (like e.g. in recentchanges.rc_ip in core). Currently, in longer IPv6 addresses, the tail is cut off, see e.g. the linked URL showing a nonsensical “2001:da8:201:1056:818f:62c9:a132”.
