how do go about blocking a particular resource that i see on the ips log?

[kb1]

so i see this log on the checkpoint:

How do i go about blocking this resource "syndication.exoclick.com" on port 53? do i need to create a url rule for that? and how would it look like (we have url filtering blade enabled but not https inspection, categorize https inspection is enabled though). And if not url filtering then how else would i block it?

Thank You.
