DNS queries from APM Edge Client

hello everyone
I confirmed that APM Edge Client requests DNS queries to msftconnecttest.com and cdn.f5.com.

One question is why do you need communication for these 2 domains?

Who can help?

thank you

    I would think that's for client binary updates (cdn) and the other is something owned by http://www.comlaude.com and hosted in Azure, as evidenced by whois:

    Often, that's for auth services from the client.
