Question about the localhost routing

[oooo-ps]

Hi there!

I recently launched βtracker - BitTorrent web-aggregator with the peers scrape feature.

Build-in scraper is using UDP protocol, to update the peers from LOCAL tracker.

Thoughts: should I really use the 127.0.0.1 address for these requests, or can I simply define the local 0200::/7 one? Will it not route the packets over the public peers? I have just experimentally launched the instance configured to the 0200::/7 tracker, which is running on localhost, and it seems to be as fast as if I were connecting directly to 127.0.0.1.

Here is the online instance, btw:
