External ipaddress 23.35.182.93 is getting incorrectly mapped to a rule "Permit Intranet Sites".
The rule uses a Urlcategory for Intranet sites and the destination has trust/untrust zones with a negate on one specific destination address.
What might cause the firewall to misapply rules if the dns to ipaddress mappings are effectively static?
I also have noticed on more than a few instances of policies with UrlCategory being applied incorrectly, many of which are external ipaddresses.

URL filtering != FQDN. URL filtering is looking at what's in the packet headers, FQDN is permitting based on the resolved IP address.
If you make the question more tangible I can try and give a specific answer.
Have a good day,

You can create custom objects -> URL Category, which can contain FQDNs and static ipaddresses. This is necessary to prevent URL Filtering from interfering with some sites.
