DNS Leak

Hi,

When I run a dns leak test I see my own IP, but then I also see IP 173.234.61.58 hostname chi81-026.ff.avast.com from Nobis Technology Group, LLC. Is this a valid IP from AVAST, or do I have a DNS leak?

Thanks

Looks like one of the streaming servers.

Running such test(s) without knowing how to interpret the result(s)/what do with them is useless.
