When does snort/ACID do DNS lookups

I'm looking at a series of alerts in ACID that clearly have the wrong hostname associated with the source IP. The host in question is on a DHCP subnet, and it did get a new lease recently. But alerts continue to be logged that show an old hostname. dig/nslookup on the sensor/database machine return the correct hostname. Since I'm seeing the old hostname associated with new alerts coming into the database, it would seem that it's not doing DNS lookups when the records are viewed. So, then it would seem that it must be doing the lookups when the database receives the alerts from snort. But, that doesn't seem right either since manual lookups on the sensor/database host return the correct hostname. It appears almost as though something has cached the mapping. The sensor/database host is not running client name service caching daemon. Any thoughts? Thanks. --Dave ------------------------------------------------------- This SF.Net email is sponsored by the new InstallShield X.
