Node/server is not showing on F5

Hello all , I am new in F5 and want to understand things how it is running on F5

While tracing a server it is showing me behind F5 with a vlan but when i logged to F5 and search this server in node list it is not showing there. So , be curious why this server is not showing there.

bash-2.03$ traceroute 10.52.24.20
