Hi there,
i developing a dynodes update client, for a mixed environment ipv4+ipv6
dual stack. For this it would be best to send/update the public
ipv6 instead of the temporary address.
For short
conn, _ := net.Dial("udp6", "[2001:db8::1]:80")
defer conn.Close()
localAddr := conn.LocalAddr().(*net.UDPAddr)
fmt.Printf("%v", localAddr)
gave me the temporary address.
In the Golang source
<https://github.com/golang/net/blob/master/ipv6/defs_linux.go>
IPV6_PREFER_SRC_PUBLIC
/ sysIPV6_PREFER_SRC_PUBLIC Flag is defines according to rfc5014
<https://tools.ietf.org/html/rfc5014#section-6> passing this flag should
use the public IPv6
as source address.
My problem is that i can't figure out, how and where i can set this flag.
Did someone has in example for me.
Kind regards
Marc
