Elasticsearch seems to redact/obfuscate IP addresses in index names

Hi there!
I am creating dynamic index names with logstash. The name contains dynamic content such as the date and IP address of the hosts monitored. Everything works. The indices are created with the proper name as I expected. However, when pulling the list of indices via the cat api, it seems that ES obfuscates the IP addresses as below in its response:
ip-172-31-10-110-apache2-2021.10.01 becomes -apache2-2021.10.01
ip-172.31.3.182-winlog-2021.10.01 becomes ip-x.x.x.x-2021.10.01
I would like to disable this behavior so I can curl and see what hosts I have an index for.
Thanks for the help!
