# By default, when enabling security manager, DNS lookups are cached indefinitely,
# as protection against DNS spoofing.  We set this back to the default (non-security-manager)
# value of 30 seconds, to prevent surprising behavior (e.g. nodes in cloud environments without
# static IP addresses). Users concerned about DNS spoofing should instead follow best practices:
# populating solr.shardsWhitelist, enabling TLS, etc.
