A Virtual IP (VIP) address is an IP address that is shared by both members of a HA server pool. When a member of the pool goes down, the other pool member takes over the VIP address and responds to requests sent to the VIP. The VIP and each pool member must be part of the same subnet.
SolarWinds High Availability does not support IPv6 addresses.
You have two options when choosing a VIP address.
If you lock down the IP addresses you send information to and receive information from, you must make configuration changes to your devices because the HA pool may send polling requests from one of three IP addresses.
You can use SolarWinds Network Configuration Manager to update your router and switch configurations.
