## **Best Practices**

- For maximum availability, Infoblox appliances should be deployed across as many different Availability Zones and Regions as needed.
- Promptly change the default admin password in NIOS.
- Use Name Server Groups to simplify name server assignments for DNS configurations.

## **Limitations**

The following general limitations apply for Infoblox vNIOS for GCP appliances:

- Only provides the LAN1 and MGMT (not enabled by default) interfaces.
- No High Availability (HA) support.
- No native GCP support for Anycast with NIOS.
- DHCP can be served for on-prem clients only, not for clients running in GCP.
