What is the dns cache ttl set to?

The failover mechanism for aws rds is to update the dns entry for the rds endpoint, meaning if a failover event occurs systems can re-connect using the same db url, but in order for that to work the DNS cache ttl needs to be sufficiently low to pick up the new IP address after the record is updated. According to the documentation this can be achieved by setting networkaddress.cache.ttl to a short enough duration in java.security, but I’m curious if keycloak (version 17) manually sets this to any value e.g. with

java.security.Security.setProperty("networkaddress.cache.ttl" , "60");
