    Public DNS Lookup not working properly


      Greetings all,


      I am doing some traffic monitoring using my beloved NTA module


      I have noticed that some public IP addresses in conversations do not resolve properly.


      Here is an example:


      Click on a Node > Network tab > Interface name

      but there are several that do not e.g.


      Click on the conversation between and my private endpoint (

      Total bytes.jpg

      Click on the Public IP address - it lists the country


      Click lookup




      Is there a setting that has to be configured for external DNS lookups?
