server connectivity to function properly, ensure that the following are in place:
All destination domains, IPs, and ports listed in the following table must be available in your firewall.
Do not enable SSL inspection in your firewall for any of the destination domains and IPs.
Source | Destinations | Destination IPs
| Protocol | Destination | Description |
|---|---|---|---|---|---|
Universal DDI | US Region
EU Region
| US Region dns.bloxone.infoblox.com
http://csp.infoblox.com
cp.noa.infoblox.com
grpc.csp.infoblox.com
app.noa.infoblox.com
EU Region dns.bloxone.eu.infoblox.com
http://csp.eu.infoblox.com
cp.noa.eu.infoblox.com
app.noa.eu.infoblox.com
| TCP | 443
| Allow these IP addresses on the firewall for the NIOS-X servers to connect to the Infoblox Portal, and to ensure Universal DDI services function properly in the respective regions. |
NIOS-X Servers DNS Forwarding Proxy
| threatdefense.bloxone.infoblox.com threatdefense.infoblox.com (and all subdomains) ope.infobloxtd.com (and all subdomains) Note that this destination domain is required only if you plan to use the “Local On-Prem resolution” feature. Note: Communication with these destinations will bypass any proxy server setting. In other words, if you configure a proxy, the DNS forwarding proxy service (threatdefense.bloxone.infoblox.com:443) is bypassed on the proxy. If you configure a proxy, the Universal DDI service destination (dns.bloxone.infoblox.com:443) is bypassed on the proxy. | US and EU Regions Anycast IPs (IPv4 and IPv6)
For geo-specific IP addresses, refer to the Infoblox geo-based Anycast IPs for POPs table in Forwarding DNS Traffic to Infoblox Platform. | TCP
| 443 53
| Infoblox uses 52.119.40.100 as the default local resolver for all NIOS-X servers. However, you can use your own local resolver to resolve the destination domains. |
NIOS-X Servers | US Region
EU Region http://csp.eu.infoblox.com
| US Region A complete list of the US region IP addresses is available in a JSON file by clicking this link. EU Region A complete list of the EU region IP addresses is available in a JSON file by clicking this link. If the server type is NIOS, do the following:
http://csp.infoblox.com
HTTP proxy configured on NIOS-X server When a HTTP proxy is configured on NIOS-X server, Data Connector is able to pull the log data from Infoblox cloud source through configured proxy. However, do note that as of now the logs sent from data connector to the configured destination will still bypass the proxy. | TCP
| 443
| All listed IPs require TCP 443 port be open when being used. |
End Client | N/A | Redirect IPs: For IPv4:
For IPv6:
| TCP | 443 or 80 | For redirect purposes. A client/end user should be connecting to the redirect server. |
NIOS-X Servers | ntp.ubuntu.com (optional) http://pool.ntp.org (optional) | N/A | UDP | 123 | For NTP server synchronization. Needed only when ESXi time sync is disabled. This is optional. |
Admin User Connectivity Requirements
Source | Destinations | Destination IPs (if applicable) | Protocol | Destination | Description |
|---|---|---|---|---|---|
Infoblox admins | US Region
http://auth.infoblox.com
http://cdnjs.cloudflare.com
EU Region
| N/A | TCP (TLS) | 443 |

Port Usage for Infoblox Services
The following table lists the ports that must be available in your firewall for Infoblox services to function properly.
All ports listed below are outbound only, except for transferring logs from NIOS to Data Connector, which requires inbound communication.
Services | Protocol | Destination Port | Description |
|---|---|---|---|
All Infoblox services | TCP
| 443
|
|
DNS Forwarding Proxy | TCP UDP
| 53
| DNS forwarding proxy uses 52.119.40.100 as the default resolver. However, you can use your own local resolver to resolve the destination domains. |
DHCP server | UDP | 68 | N/A |
Infoblox DNS | TCP | 443 | For Universal DDI authoritative DNS cloud services.
|
Sending peer of the DHCP HA (High Availability) | TCP | 647 | This is an incoming port for the HA (High Availability) feature. The receiving peer must be able to receive traffic on the port, and the sending peer must be able to send traffic to the port, generally from other random ports. |
Sending peer of the DHCP cluster | TCP
| 647 or 847 | For DHCP cluster load balancing. The receiving peer must be able to receive traffic on the port, and the sending peer must be able to send traffic to the port, generally from other random ports. |
Data Connector | TCP | 22 | Open this port if you want to send data using SCP from the Infoblox NIOS appliance (if configured) to Data Connector. The NIOS UI provides a mechanism to filter the domains it sends to Data Connector. Since NIOS is sending cache logs, when configuring NIOS for use with Data Connector, make sure to configure Data Connector to exclude internal corporate and authoritative domains (*.<corp>/Authorititative). By excluding corporate and authoritative domains, internal traffic logs will not be added. Required for incoming SCP data transfer from NIOS to Data Connector when deployed as a container. When you deploy Data Connector as a container, ensure that there are no SSH processes listening on port 22. You must terminate these SSH processes for Data Connector to collect data from NIOS. If you deploy Data Connector as a container, ensure that there are no SSH processes listening on port 22. You must terminate these SSH processes for Data Connector to collect data from NIOS. |
Data Connector | TCP | 514 | Open this port if you want to send syslog and secure syslog for RPZ from the Infoblox NIOS appliance (if configured) to Data Connector. Note: Port 514 is an insecure port. The NIOS UI provides a mechanism to filter the domains it sends to Data Connector. Since NIOS is sending cache logs, when configuring NIOS for use with Data Connector, make sure to configure Data Connector to exclude internal corporate and authoritative domains (*.<corp>/Authoritative). By excluding corporate and authoritative domains, internal traffic logs will not be added. Required for Data Connector secure syslog for RPZ hits data. If you deploy Data Connector as a container, ensure that this port is not used by other processes. If you deploy Data Connector as a container, ensure that this port is not used by other processes for Data Connector to collect data from NIOS. |
Data Connector | TCP | 6514 | Open this port if you want to send syslog and secure syslog for RPZ from the Infoblox NIOS appliance (if configured) to Data Connector. The NIOS UI provides a mechanism to filter the domains it sends to Data Connector. Since NIOS is sending cache logs, when configuring NIOS for use with Data Connector, make sure to configure Data Connector to exclude internal corporate and authoritative domains (*.<corp>/Authoritative). By excluding corporate and authoritative domains, internal traffic logs will not be added. Used for transferring syslog data from NIOS to Data container. Port 6514 is a default secure port. If you deploy Data Connector as a container, ensure that this port is not used by other processes. If you deploy Data Connector as a container, ensure that this port is not used by other processes for Data Connector to collect data from NIOS. |
