 ====== Infoblox Best Practice ======
 If you are configuring a dual-stack network for the host, you must set the minimum MTU value for the IPv4 address to 1280; if you do not, the IPv6 address will not be functional.
+===== NIST Best Practice for DNS =====

+===== RPZ =====
+When you use RPZ to download Threat Feeds from a provider (e.g. Infoblox, etc), make sure that at the first RPZ feed in the list is a local feed that lists your critical internal domains and RFC1918 (and other networks that you use), set the action to allow without logging. This will prevent your internal systems from being impacted by erroneous data in the providers feed.
 ===== NIOS Logging =====
 Under Grid Properties > General > Basic > Audit Logging you can set "Brief", "Detailed", "WAPI Detailed". Setting to Brief instead of Detailed can (and has) hampered Infoblox support in establishing exact root cause of issues.
+Under Grid Properties > Monitoring > Basic make sure you tick Copy Audit Log Message to Syslog. Because it is syslog that can be copied of to SIEM server, this is how you ensure a longer copy of audit logs.
 ===== DDI =====
   * DNS - If the Round Trip Time (RTT) between client and DNS server is greater than 200ms, then the user starts to notice.
