Denton Gentry	b46c5ae82a	cmd/sniproxy: draw the rest of the DNS owl. ... Add a DNS server which always responds as its own IP addresses. Additionally add a tsnet TailscaleIPs() function to return the IP addresses, both IPv4 and IPv6.

Brad Fitzpatrick	0f4359116e	tsnet: add UDP support to Server.Listen ... No ListenPacket support yet, but Listen with a udp network type fit easier into netstack's model to start. Then added an example of using it to cmd/sniproxy with a little udp :53 handler. No tests in tsnet yet because we don't have support for dialing over UDP in tsnet yet. When that's done, a new test can test both sides. Updates #5871 Updates #1748 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2023-03-05 12:40:13 -08:00
