12054	Comments: Data truncated for column 'ip_address' when using IPv6	Kenneth Falck	nobody	"The contrib.comments system creates the django_comments.ip_address field as a char(15), which doesn't fit an IPv6 REMOTE_ADDR. Entering a comment causes the MySQL error ""Data truncated for column 'ip_address'.""

I believe IPv6 needs at least 39 characters to store any IP address. After manually modifying the field length in MySQL, the comment system works again.
