Strange subdomain found during nmap scan

Can anyone explain this? I found and F5 load balancer with a strange subdomain of my company. It looks like whatif..com.

I immediately sandboxed it only to find it redirects to are company auth portal. I’m brand new to the company and don’t want to sound dumb. I’m sure this is an iRule for pooling but I’m not smart enough to back that statement up. Or the statement I just said makes no sense. Either way I need help.
