I couldn't figure out how to make a udp socket bound to a port of my choosing on the local machine, to use for listening for incoming connections.

I assume you meant "incoming datagrams" and not "incoming connections".

import std.stdio, std.socket;

void main()
{
    bool ipv6;
    ushort port = 1000;

    Address bindAddress;
    if(ipv6)
    {
        bindAddress = new Internet6Address(Internet6Address.ADDR_ANY, port);
    }
    else
    {
        bindAddress = new InternetAddress(InternetAddress.ADDR_ANY, port);
    }


    Socket udpSocket = new Socket(bindAddress.addressFamily, SocketType.DGRAM, ProtocolType.UDP);
    udpSocket.bind(bindAddress);
    writefln("listening for udp datagrams on port %s", port);

    ubyte[3000] buffer;
    while(true)
    {
        Address from;
        auto length = udpSocket.receiveFrom(buffer, from);
        writefln("received %s byte datagram from %s", length, from);
    }
}
