Hence the dangers of tracking IP addresses for identity. If that user
has a static IP, then she's most probably lying. OTOH, if her ISP doles
out dynamic IPs, I'd venture to guess that the odds of her getting the
same IP on different dates and leaving another comment is highly
unlikely. Dynamic IP ranges can be quite wide ranging. Some ISPs say
they use dynamic IPs. However, depending on the actual equipment and
circumstances involved, users may never (or rarely) see their IP change.

Since you say the comment was 'anonymous', you may come across as being
hypocritical if you press the issue. Do you have a privacy policy? Tread
