Types ¶
type Resolver ¶
type Resolver struct {
// Addr is the address of the DNS resolver, one of:
// - A plain IP address for a "classic" UDP+TCP DNS resolver.
// This is the common format as sent by the control plane.
// - An IP:port, for tests.
// - "https://resolver.com/path" for DNS over HTTPS; currently
// as of 2022-09-08 only used for certain well-known resolvers
// (see the publicdns package) for which the IP addresses to dial DoH are
// known ahead of time, so bootstrap DNS resolution is not required.
// - "http://node-address:port/path" for DNS over HTTP over WireGuard. This
// is implemented in the PeerAPI for exit nodes and app connectors.
// - [TODO] "tls://resolver.com" for DNS over TCP+TLS
Addr string `json:",omitempty"`
// BootstrapResolution is an optional suggested resolution for the
// DoT/DoH resolver, if the resolver URL does not reference an IP
// address directly.
// BootstrapResolution may be empty, in which case clients should
// look up the DoT/DoH server using their local "classic" DNS
// resolver.
//
// As of 2022-09-08, BootstrapResolution is not yet used.
BootstrapResolution []netip.Addr `json:",omitempty"`
// UseWithExitNode designates that this resolver should continue to be used when an
// exit node is in use. Normally, DNS resolution is delegated to the exit node but
// there are situations where it is preferable to still use a Split DNS server and/or
// global DNS server instead of the exit node.
UseWithExitNode bool `json:",omitempty"`
}
Resolver is the configuration for one DNS resolver.
func (*Resolver) Clone ¶
Clone makes a deep copy of Resolver. The result aliases no memory with the original.
func (*Resolver) IPPort ¶ added in v1.24.0
IPPort returns r.Addr as an IP address and port if either r.Addr is an IP address (the common case) or if r.Addr is an IP:port (as done in tests).
func (*Resolver) View ¶ added in v1.26.0
func (p *Resolver) View() ResolverView
View returns a read-only view of Resolver.
type ResolverView ¶ added in v1.26.0
type ResolverView struct {
// contains filtered or unexported fields
}
ResolverView provides a read-only view over Resolver.
Its methods should only be called if `Valid()` returns true.
func (ResolverView) Addr ¶ added in v1.26.0
func (v ResolverView) Addr() string
Addr is the address of the DNS resolver, one of:
- A plain IP address for a "classic" UDP+TCP DNS resolver. This is the common format as sent by the control plane.
- An IP:port, for tests.
- "https://resolver.com/path" for DNS over HTTPS; currently as of 2022-09-08 only used for certain well-known resolvers (see the publicdns package) for which the IP addresses to dial DoH are known ahead of time, so bootstrap DNS resolution is not required.
- "http://node-address:port/path" for DNS over HTTP over WireGuard. This is implemented in the PeerAPI for exit nodes and app connectors.
- [TODO] "tls://resolver.com" for DNS over TCP+TLS
func (ResolverView) AsStruct ¶ added in v1.26.0
func (v ResolverView) AsStruct() *Resolver
AsStruct returns a clone of the underlying value which aliases no memory with the original.
func (ResolverView) BootstrapResolution ¶ added in v1.26.0
func (v ResolverView) BootstrapResolution() views.Slice[netip.Addr]
BootstrapResolution is an optional suggested resolution for the DoT/DoH resolver, if the resolver URL does not reference an IP address directly. BootstrapResolution may be empty, in which case clients should look up the DoT/DoH server using their local "classic" DNS resolver.
As of 2022-09-08, BootstrapResolution is not yet used.
func (ResolverView) Equal ¶ added in v1.50.0
func (v ResolverView) Equal(v2 ResolverView) bool
func (ResolverView) MarshalJSON ¶ added in v1.26.0
func (v ResolverView) MarshalJSON() ([]byte, error)
MarshalJSON implements jsonv1.Marshaler.
func (ResolverView) MarshalJSONTo ¶ added in v1.88.0
func (v ResolverView) MarshalJSONTo(enc *jsontext.Encoder) error
MarshalJSONTo implements jsonv2.MarshalerTo.
func (*ResolverView) UnmarshalJSON ¶ added in v1.26.0
func (v *ResolverView) UnmarshalJSON(b []byte) error
UnmarshalJSON implements jsonv1.Unmarshaler.
func (*ResolverView) UnmarshalJSONFrom ¶ added in v1.88.0
func (v *ResolverView) UnmarshalJSONFrom(dec *jsontext.Decoder) error
UnmarshalJSONFrom implements jsonv2.UnmarshalerFrom.
func (ResolverView) UseWithExitNode ¶ added in v1.88.0
func (v ResolverView) UseWithExitNode() bool
UseWithExitNode designates that this resolver should continue to be used when an exit node is in use. Normally, DNS resolution is delegated to the exit node but there are situations where it is preferable to still use a Split DNS server and/or global DNS server instead of the exit node.
func (ResolverView) Valid ¶ added in v1.26.0
func (v ResolverView) Valid() bool
Valid reports whether v's underlying value is non-nil.
