Sonar IP Addressing

Sonar runs as a series of containers in Microsoft Azure, with front-end devices and NAT handling traffic to and from each instance. Your instance’s IP addresses depend on which Azure data center hosts it. Most instances are in the US data center, and Canadian instances are in the CA data center.

Use the addresses in this article to allow Sonar traffic through your firewall and network management devices. This matters most if Sonar works with your DHCP or RADIUS servers.

Instance IP Addresses

Find your instance’s region below. Your firewall needs to allow both the ingress and egress addresses for that region.

Region
Direction
IP address
Hostname
United States
Ingress / Inbound
52.185.67.212
sonar-prod-az-1.sonar.software
United States
Egress / Outbound
20.221.112.37
20.221.114.13
52.158.209.86
sonar-prod-az-1-egress.sonar.software
Canada
Ingress / Inbound
20.104.33.4
sonar-prod-canadaca-1.sonar.software
Canada
Egress / Outbound
20.104.33.4
4.172.7.128/28 (4.172.7.128 – 4.172.7.143)
sonar-prod-canadaca-1.sonar.software (20.104.33.4 only)
Outbound traffic from Canadian instances can come from 20.104.33.4 or from any address in the 4.172.7.128/28 block. Add the full /28 block to your allow lists, not individual addresses, so Sonar traffic isn’t blocked when the source address changes.

Ingress vs. Egress

Term
Meaning
Ingress / Inbound
The address you point at when a connection starts outside your Sonar instance and is headed into it.
Egress / Outbound
The address you'll see when your Sonar instance starts a connection to something outside it.

Where to Add These Addresses

If Sonar works with your DHCP or RADIUS servers, add the ingress and egress addresses for your region to both your firewall and any network management devices that communicate with Sonar. If these addresses are missing, Sonar can’t reach those devices, and they can’t reach Sonar.

For an overview of the ways Sonar can work with your DHCP and RADIUS servers, see IP Assignments & Sonar.

Additional IP Addresses

Depending on your setup, you may also need to allow the following addresses.
