I’ve see 34.94.207.175 in my private network, which peer id is same as the first 10 digits of my network id.

It has been marked as LEAF in zerotier-cli listppers, and it was not listed in my.zerotier.com.

That’s a network controller, hence sharing the first 10 digits of your network ID.

Also, peers listed by listpeers or peers are not necessarily members of your network. They’re other machines running ZeroTier that yours knows about.
