Configure resolving IPv4 and IPv6 addresses to DNS hostnames in SolarWinds NTA

Enabling the option Resolve IPv4 and IPv6 addresses to DNS hostnames in SolarWinds NTA decreases the amount of database memory used to store DNS information and the read and write load on your SQL server associated with domain name resolution.

With the option Resolve IPv4 and IPv6 addresses to DNS hostnames enabled, domain names are only resolved for device IP addresses that are actually displayed in SolarWinds NTA resources. Since they require persistent DNS resolution to calculate statistics, Top XX IPv4 Domains, Top XX IPv4 Traffic Destinations by Domain (report), and Top XX IPv4 Traffic Sources by Domain (report) become unavailable with this setting.

  1. Click Settings > All Settings.
  2. Under Product Specific Settings, click NTA Settings.
  3. Under DNS and NetBIOS Resolution, select Resolve IPv4 and IPv6 addresses to DNS hostnames.
  4. Click Save.
