Hello,

I can confirm the same issue here. 

note: I've tried a reverse lookup of these ip address from the server shell and they resolve successfully from command line.

Sometimes you need to refresh after visiting this page in order to see the updated rDNS entries. This is because we don't check the rDNS until the page is visited, anything you see as "Loading..." should hopefully be filled in on the next visit to the page. I'll admit this is not great behavior and it's something we should look into fixing. I believe this is on our bugs list.

EDIT: Not on the list but is now.

Thanks for the reply Matt!  I tried refreshing the page but the same behavior is seen.  Thanks once again!

Hi Matt,

Tried refresh / logout / login. They still display "Loading..."

edit: seems to me it only affects "Top Inbound IP Addresses". 

"Top Outbound IP Addresses" is always OK (except some with N/A but I guess it means there is not reverse DNS for these)

Kind regards
