Why trusted source engine does not resolve fqdn ?
126.96.36.199 categorized as "Malicious sites"
dl.fileszstore.com - is uncategorized (but resolved to 188.8.131.52)
dl.filevfstore.com - is uncategorized (but resolved to 184.108.40.206)
I get list of all sites that hosted on 220.127.116.11 and all of them related to "Malicious downloads"
So question is: how to categorize sites using resolving names to ip ?
in most cases a reverse resolution from an IP to a hostname is not going to give you a good result. Shared hosting (50k domains on 1 ip) is a comming thing.
by default the web gateway will not a lookup of the IP for the categorization of a host.
In web gateway 7 you could do this though. you could create a rule that says 'if hostname is uncategorized, do a dns lookup and then try to categorize again". there are even options directly in the trustedsource engine. but unfortunately nothing that you could do on web gateway 6.x
