Hi,

Hmm, I suppose you've got a point - but FQDNs are sure helpful in determining whence visitors came.
You ought to take it one stage further and *never* log names (FQN or host) always IP Address. Your dns may be compromised while you are trying to log.
And AFAIK only expensive log analysers (e.g. WebTrends) resolve IPs while analysing logs.
This is the proper way to do it and it should be analysed on a safe host away from the live environment. John
