Tool to monitor a network interface for IP changes and publish an mDNS service.
To publish `docker.local` and map it to the IP of interface `eth0`:
```
./mdnstool -if eth0
```
Options:
```
Usage of ./mdnstool:
-hostname string
Hostname - must be FQDN and end with . (default "docker.local.")
-if string
Network interface to bind multicast listener to. This interface will be monitored for IP changes. (default "eth0")
-info string
TXT service description (default "Moby")
-instance string
Instance description (default "Moby")
-port int
Service port (default 22)
-service string
SRV service type (default "_ssh._tcp")
```
To build for Linux:
```
GOOS=linux GOARCH=386 go build -v
```

// Package ipv4 implements IP-level socket options for the Internet
// Protocol version 4.
//
// The package provides IP-level socket options that allow
// manipulation of IPv4 facilities. The IPv4 and basic host
// requirements for IPv4 are defined in RFC 791, RFC 1112 and RFC
// 1122.
//
//
// Unicasting
//
// The options for unicasting are available for net.TCPConn,
// net.UDPConn and net.IPConn which are created as network connections
// that use the IPv4 transport. When a single TCP connection carrying
// a data flow of multiple packets needs to indicate the flow is
// important, ipv4.Conn is used to set the type-of-service field on
// the IPv4 header for each packet.
//
// ln, err := net.Listen("tcp4", "0.0.0.0:1024")
// if err != nil {
// // error handling

// for {
// c, err := ln.Accept()
// if err != nil {
// // error handling
// }
// go func(c net.Conn) {
// defer c.Close()
//
// The outgoing packets will be labeled DiffServ assured forwarding
// class 1 low drop precedence, as known as AF11 packets.
//
// if err := ipv4.NewConn(c).SetTOS(DiffServAF11); err != nil {
// // error handling
// }
// if _, err := c.Write(data); err != nil {
// // error handling
// }
// }(c)
// }
//
//
// Multicasting
//
// The options for multicasting are available for net.UDPConn and
// net.IPconn which are created as network connections that use the
// IPv4 transport. A few network facilities must be prepared before
// you begin multicasting, at a minimum joining network interfaces and
// multicast groups.
//
// en0, err := net.InterfaceByName("en0")
// if err != nil {
// // error handling
// }
// en1, err := net.InterfaceByIndex(911)
// if err != nil {

// }

// First, an application listens to an appropriate address with an
// appropriate service port.
//
// c, err := net.ListenPacket("udp4", "0.0.0.0:1024")
// if err != nil {
// // error handling
// }
// defer c.Close()
//
// Second, the application joins multicast groups, starts listening to
// the groups on the specified network interfaces. Note that the
// service port for transport layer protocol does not matter with this
// operation as joining groups affects only network and link layer
// protocols, such as IPv4 and Ethernet.
//
// p := ipv4.NewPacketConn(c)

// // error handling
// }
// if err := p.JoinGroup(en1, &net.UDPAddr{IP: group}); err != nil {
// // error handling
// }
//
// The application might set per packet control message transmissions
// between the protocol stack within the kernel. When the application
// needs a destination address on an incoming packet,
// SetControlMessage of ipv4.PacketConn is used to enable control
// message transmissons.
//
// if err := p.SetControlMessage(ipv4.FlagDst, true); err != nil {
// // error handling
// }
//
// The application could identify whether the received packets are
// of interest by using the control message that contains the
// destination address of the received packet.
//
// b := make([]byte, 1500)
// for {
// n, cm, src, err := p.ReadFrom(b)
// if err != nil {
// // error handling
// }
// if cm.Dst.IsMulticast() {
// if cm.Dst.Equal(group)
// // joined group, do something
// } else {
// // unknown group, discard
// continue
// }
// }
//
// The application can also send both unicast and multicast packets.
//
// p.SetTOS(DiffServCS0)
// p.SetTTL(16)

// // error handling
// }
// p.SetMulticastTTL(2)
// if _, err := p.WriteTo(data, nil, dst); err != nil {
// // error handling
// }
// }
// }
//
//
// More multicasting
//
// An application that uses PacketConn or RawConn may join multiple
// multicast groups. For example, a UDP listener with port 1024 might
// join two different groups across over two different network
// interfaces by using:
//
// c, err := net.ListenPacket("udp4", "0.0.0.0:1024")
// if err != nil {
// // error handling
// }
// defer c.Close()
// p := ipv4.NewPacketConn(c)
// if err := p.JoinGroup(en0, &net.UDPAddr{IP: net.IPv4(224, 0, 0, 248)}); err != nil {
// // error handling

// // error handling
// }
// if err := p.JoinGroup(en1, &net.UDPAddr{IP: net.IPv4(224, 0, 0, 249)}); err != nil {
// // error handling
// }
//
// It is possible for multiple UDP listeners that listen on the same
// UDP port to join the same multicast group. The net package will
// provide a socket that listens to a wildcard address with reusable
// UDP port when an appropriate multicast address prefix is passed to
// the net.ListenPacket or net.ListenUDP.
//
// c1, err := net.ListenPacket("udp4", "224.0.0.0:1024")
// if err != nil {
// // error handling
// }
// defer c1.Close()

// if err := p2.JoinGroup(en0, &net.UDPAddr{IP: net.IPv4(224, 0, 0, 248)}); err != nil {

// Package ipv6 implements IP-level socket options for the Internet
// Protocol version 6.
//
// The package provides IP-level socket options that allow
// manipulation of IPv6 facilities. The IPv6 and socket options for
// IPv6 are defined in RFC 2460, RFC 3493 and RFC 3542.
//
//
// Unicasting
//
// The options for unicasting are available for net.TCPConn,
// net.UDPConn and net.IPConn which are created as network connections
// that use the IPv6 transport. When a single TCP connection carrying
// a data flow of multiple packets needs to indicate the flow is
// important, ipv6.Conn is used to set the traffic class field on the
// IPv6 header for each packet.

// // error handling
// }
// if _, err := c.Write(data); err != nil {
// // error handling
// }
// }(c)
// }
//
//
// Multicasting
//
// The options for multicasting are available for net.UDPConn and
// net.IPconn which are created as network connections that use the
// IPv6 transport. A few network facilities must be prepared before
// you begin multicasting, at a minimum joining network interfaces and
// multicast groups.

// appropriate service port.
//
// c, err := net.ListenPacket("udp6", "[::]:1024")
// if err != nil {
// // error handling
// }
// defer c.Close()
//
// Second, the application joins multicast groups, starts listening to
// the groups on the specified network interfaces. Note that the
// service port for transport layer protocol does not matter with this
// operation as joining groups affects only network and link layer
// protocols, such as IPv6 and Ethernet.

// The application might set per packet control message transmissions
// between the protocol stack within the kernel. When the application
// needs a destination address on an incoming packet,
// SetControlMessage of ipv6.PacketConn is used to enable control
// message transmissons.
//
// if err := p.SetControlMessage(ipv6.FlagDst, true); err != nil {

// if rcm.Dst.IsMulticast() {
// if rcm.Dst.Equal(group)
// // joined group, do something
// } else {

// // error handling
// }
// }
// }
//
//
// More multicasting
//
// An application that uses PacketConn may join multiple multicast
// groups. For example, a UDP listener with port 1024 might join two
// different groups across over two different network interfaces by
// using:
//
// c, err := net.ListenPacket("udp6", "[::]:1024")
// if err != nil {
// // error handling
// }
// defer c.Close()
// p := ipv6.NewPacketConn(c)

// // error handling
// }
// if err := p.JoinGroup(en1, &net.UDPAddr{IP: net.ParseIP("ff02::2:114")}); err != nil {
// // error handling
// }
//
// It is possible for multiple UDP listeners that listen on the same
// UDP port to join the same multicast group. The net package will
// provide a socket that listens to a wildcard address with reusable
// UDP port when an appropriate multicast address prefix is passed to
// the net.ListenPacket or net.ListenUDP.
//
// c1, err := net.ListenPacket("udp6", "[ff02::]:1024")
// if err != nil {
// // error handling

// defer c1.Close()
// c2, err := net.ListenPacket("udp6", "[ff02::]:1024")
// if err != nil {

// defer c2.Close()
// p1 := ipv6.NewPacketConn(c1)
// if err := p1.JoinGroup(en0, &net.UDPAddr{IP: net.ParseIP("ff02::114")}); err != nil {

// if err := p2.JoinGroup(en0, &net.UDPAddr{IP: net.ParseIP("ff02::114")}); err != nil {
// // error handling

//
// Also it is possible for the application to leave or rejoin a
// multicast group on the network interface.
