We are pleased to announce availability of Internet Protocol version 6 (IPv6) support for communication between sensors and the Tenable.io site.

For environments that support IPv6 only, please ensure the following prerequisites are met in order to use IPv6 for sensor to Tenable.io communication. 

1. Nessus Agent 8.1.0+
2. Nessus Scanner 8.12.0+
3. Corporate firewall rules allow communicating to sensor.cloud.tenable.com domain OR if you are using allowed IPs, add the following two IPv6 addresses to the list.

2606:4700:7::a29f:8153

2606:4700:7::a29f:8253

Please use the below instructions when linking Nessus Agents or Scanners.

To link a Nessus Agent or Scanner to Tenable.io over IPv6, you must link to sensor.cloud.tenable.com:443.

To link a new agent over IPv6, use:

nessuscli agent link --host=sensor.cloud.tenable.com --port=443 --key=yourlinkingkeyhere

To update an already linked agent, use:

nessuscli fix --secure --set ms_server_ip=sensor.cloud.tenable.com

To link a new scanner over IPv6, use:

nessuscli managed link --host=sensor.cloud.tenable.com --port=443 --key=yourlinkingkeyhere

To update an already linked scanner, use:

nessuscli fix --secure --set ms_server_ip=sensor.cloud.tenable.com
