type TLSPool ¶

type TLSPool struct {
	// contains filtered or unexported fields
}

TLSPool is a connections pool for the DNS-over-TLS Upstream.

Example:

pool := TLSPool{Address: "tls://1.1.1.1:853"}
netConn, err := pool.Get()
if err != nil {panic(err)}
c := dns.Conn{Conn: netConn}
q := dns.Msg{}
q.SetQuestion("google.com.", dns.TypeA)
log.Println(q)
err = c.WriteMsg(&q)
if err != nil {panic(err)}
r, err := c.ReadMsg()
if err != nil {panic(err)}
log.Println(r)
pool.Put(c.Conn)

func (n *TLSPool) Get() (net.Conn, error)

func (n *TLSPool) Put(c net.Conn)

type Upstream ¶

type Upstream interface {
	Exchange(m *dns.Msg) (*dns.Msg, error)
	Address() string
}

Upstream is an interface for a DNS resolver

func AddressToUpstream(address string, bootstrap string) (Upstream, error)
