Inbound Traffic - Routes
So if you advertise 220.127.116.11/19 to AboveNet, -
If you’re a network peer, they only re-announce 18.104.22.168/19 to customers (and use it internally);
If you’re a transit peer/customer, they announce 22.214.171.124/19 to all of their network peers.
That’s how you get global *inbound* reachability.
