Package flowtrack contains types for tracking TCP/UDP flows by 4-tuples.

Package interfaces contains helpers for looking up system network interfaces.

Package netcheck checks the network conditions from the current host.

Package netstat returns the local machine's network connection table.

Package packet contains packet parsing and marshaling utilities.

Package STUN generates STUN request packets and parses response packets.

Package tlsdial originally existed to set up a tls.Config for x509 validation, using a memory-optimized path for iOS, but then we moved that to the tailscale/go tree instead, so now this package does very little.

Package tsaddr handles Tailscale-specific IPs and ranges.

Package tshttpproxy contains Tailscale additions to httpproxy not available in golang.org/x/net/http/httpproxy.
