dns: remove default 8.8.8.8 DNS server Now that DNS servers are pulled in from the DHCP config, this is unnecessary. Moreover, it's harmful: getaddrinfo will attempt to reach 8.8.8.8 before DHCP has completed. This can result in the DNS client keeping a UDP endpoint with a bad source IP address open for many seconds, blocking a real connection. Without 8.8.8.8, getaddrinfo immediately fails before DHCP because there are no known DNS servers. It does not try to make a connection until the real local IP is setup.

Netstack is a network stack written in Go.
Try it out on Linux by installing the tun_tcp_echo demo:
go install github.com/google/netstack/tcpip/sample/tun_tcp_echo
Create a TUN device with:
[sudo] ip tuntap add user <username> mode tun <device-name> [sudo] ip link set <device-name> up [sudo] ip addr add <ipv4-address>/<mask-length> dev <device-name>
Then run with:
tun_tcp_echo <device-name> <ipv4-address> <port>
