### BT(BitTorrent) Tracker Service
I run a public BitTorrent Tracker server: [http://tracker.renfei.net:8080/announce ](http://tracker.renfei.net:8080/announce ), which assists in communication between peers using the BitTorrent protocol, helps speed up BitTorrent downloads.
### Internet IP Address Query Service
Since the network may use multi-layer NAT address translation, IP address query for Internet egress:
* [ip.renfei.net ](http://ip.renfei.net ) : IPv4 and IPv6, IPv6 is generally preferred, depending on the DNS resolution of the client.
* [ipv4.renfei.net ](http://ipv4.renfei.net ) : IPv4 Only.
* [ipv6.renfei.net ](http://ipv6.renfei.net ) : IPv6 Only.
