Hi,
In many software projects I have to get the address family of a net.IP
object. I always duplicate the following code:
func isIPv4(ip net.IP) bool {
return len(ip) == net.IPv4len || (len(ip) > 11 && isZeros(ip[0:10]) &&
ip[10] == 0xff && ip[11] == 0xff)
}
func isZeros(ip net.IP) bool {
for _, b := range ip {
if b != 0 {
return false
}
}
return true
}
Instead it would be very very useful to have a Family(), IsIPv4 or IsIPv6
function on net.IP.
What is your opinion on that?
