OpenRead modifications: keep only Vietnam (VN), merge adjacent ranges,
and encode IPv4/IPv6 bounds as fixed-width hexadecimal for an offline PHP lookup.
The data is used only by the website; it is not bundled into the iOS app.
Lite data has reduced coverage/accuracy and is refreshed monthly upstream.

Cloudflare proxy ranges come from https://www.cloudflare.com/ips-v4 and
https://www.cloudflare.com/ips-v6. They are used only to authenticate the peer
before accepting CF-Connecting-IP; no country header is used.
