DNS resolution for websites in NTA

Hi,

When you look at SolarWind's demo NTA page on their website, website names are resolved so that you see people accessing youtube.com, wikipedia.org, and so on. But our NTA doesn't resolve websites. To test it out, I went to Youtube and watched videos, then checked NTA to find the conversation between my workstation and Youtube. It showed up as a conversation between my workstation and 173.194.9.217. I'm not sure if this is a DNS issue or an NTA issue (or maybe a NetFlow issue?). Any suggestions on how to get those website names to show up in our NTA?

Thanks.

Because 173.194.9.217 doesn't resolve.

Swine,

I'm not able to resolve 173.194.9.217 either. Also, if you don't have any addresses resolving, you should check the name resolution settings. Go to Settings - NTA Settings and scroll to about mid page. You should see the section matching the screenshot below.

I guess it's just a reverse DNS issue. NTA is pulling its DNS resolutions from our local DNS server, and if our DNS can't resolve 173.194.9.217 to youtube.com, then NTA is just going to show the IP address.

I have this same problem but reverse DNS is working fine.

From the box running NTA the reverse DNS for every one of its top xx endpoints resolves perfectly fine using the nslookup command util. But nothing shows in NTA except IP addresses.

Even devices which are managed nodes in OPM (including the Orion server itself) just display with IP addresses in NTA.

I have enabled all options in the NetBIOS/DNS section including persistent lookups.

Any advice on what to do next to get this working?
