How can I test my threat list is working?

All, I just enabled a threat list in Splunk ES. First time. I guess it's working, no error message. emerging_threats_compromised_ip_blocklist threatlist Emerging Threats compromised IPs blocklist https://rules.emergingthreats.net/blockrules/compromised-ips.txt\ How do I test this? How can generate an event against it?
