I guess your tool probably asks a faulty caching nameserver for the NS records of cnn.com - there are several misguided implementations that cache for a longer period than the TTL of the record states. Having said that and beeing a hostmaster for a large german broadband ISP i am indeed quite thankful for Microsoft ignoring low TTLs in most Windows XP installations especially as todays drones do no seem to care about asking proper IN MX questions. ;-) Stefan -- My software never has bugs.
